Yup, looks like "intentional" is the right word. 

One of their Improvements and Battle Fixes (#4 Fixed a bug that caused the Hydra’s Almighty Decay skill not to destroy enemies’ MAX HP up to 75%.) took away Nekmo, RG, Husk, etc as usable champs.

This video from HH Gaming explains it. Hope they fix their fix.

REVERT THIS "BUGFIX" IMMEDIATELY PLARIUM!! | Raid: Shadow Legends - YouTube 

Once again, you overshadow strong new content, with a horrible change. Hydra change has taken over excitement for live arena. You roll the patch out on the day before hydra resets so people don't even have time to consider changes!?!? You adjust difficulty of hydra to make more manageable but then come back now and give hydra a strong buff that makes certain champs useless with no heads up?? You buff a champion like Teela but then buff Decay (any bug fix this late after launch is a buff) to make her useless? Watch the HH Gaming video others referenced if you don't understand the extent of the problem you created. Anyone in our clan who hadn't used all their keys are furious today. 

This live arena "stuff" should be completely separate. I have no interest in that "mode" and to the extent the rewards to live area "players" make me uncompetitive - I would need to rage quit and spend my $$ and time elsewhere.

I await your thoughts but am concerned the meta is now leaving me.

AND PS whoever decided i would be a good beta test pilot just doesnt care to understand

So the pay-to-play-to-win game just turned into the pay-to-play beta-test game. Got it.

Looking good. Keep it up. 

Hello 

I have spent tens of thousands of dollars on this game in the last year and a half, and I'm furious about the hydra "bug fix". You had the audacity to put a summon rush out for a god tier hydra champ knowing you were going to make the part of the game he excels at unplayable minutes after his summon event ended? Disgusting. This is worse than the variety pack scam you pulled three days ago, and that was the worst I'd seen to date. You've lost my spending until it's fixed!

4. Fixed a bug that caused the Hydra’s Almighty Decay skill not to destroy enemies’ MAX HP up to 75%. 

How can you justify this FIX?

This "so called bug" has been this way since the RELEASE of HYDRA..!

Hydra was a VERY difficult part of the game to begin with, then you nerfed some aspects and put it in the "hard", but attainable category.

With this change, you have essensialy "nerfed" MANY champions, some of which I have ONLY built because they worked well in Hydra. (for 18 months)

Some champions that you recently buffed (Teela Goremane) sure seemed like you buffed her to make her usable in Hydra? Now the change you made to HYDRA make her almost useless.

Please explain how this is GOOD change for your game?

WOW...I didn't even see the "tie-in" with the Michinaki guaranteed Summon Event.  I went for it as well, and now, they have buffed Hydra.  And, YES, as @Cortavius said earlier, and so called bug fix after this long is NOT A FIX, it is a BUFF.

I see my days as a Raid player getting shorter and shorter and it sucks because I do love this game.  Please Plarium, tell me this is NOT just a MONEY GRAB for Blessings...another part of the game that you have totally dropped the ball on.

You knew about the bug for about 1 year and 4 months, then strung players and offered champions to beat the content, build them, spend resources on them, and then hit them with a "bug" fix. 

Sadly, we probably have not seen the ceiling regarding your despicable, deplorable, and predatory behavior. 

"Fixed a bug that caused the Hydra’s Almighty Decay skill not to destroy enemies’ MAX HP up to 75%. "

Roll this BS back. You done gone and broke all of our hydra teams that we paid real money on. 

Nice

Wow have you guys screwed up good this time.

1: Hydra 'bug fix' - yeah, others already pointed out the issue, as have CC's, to say nothing of the even more massive PR issue that is recent events for hydra champs right before pulling this. 

2: 'Live' Arena times - I'm on the US East Coast, and keep in mind the only reason I'm awake at the moment is I'm sick and just had a violent coughing spell that woke me up. Todays start times for US East are 3am, 6am, 10am, and 4pm - most people are respectively asleep, just getting up for work/school, at work/school, and are at school activites/work and through the end of that time, likely on thier way home and making/eating dinner. And none of the other times are exactly better, nor are any mainland US timezones any better (maybe Alaska and Hawaii have half a shot). So uh - I guess thanks for the giant middle finger to everyone in the America's on that timing?

3: Great hall, Content, Arena - Straight up, Arena is some of the worst, most frustrating, and frankly boring content in the game because either you have idiotic high speeds and stats, or ridiculous comps that can make a DEF strategy work - or you lose. I started playing right before the pandemic started so like what 4 years now? My great hall is still not done, because I've had to play through several arena breaks, because even if I get through 25 per day when I manage to hold Gold IV/V without gettign randomly kicked down a tier or two and have to fight back up - I only win so many because even with a 300 speed Arbiter, before speed lead, I end up smoked in fights by teams that somehow leave me in the dust with no speed lead, sometimes not even a booster, that go first with speed levels I didn't know even existed. And now, you clearly wanna balance content off the newest addition to the great hall. Where hey - the times are screwed for a lot of people so they can't really even try and participate to earn toward it. Look, you wanna add lets say fragments for past fragment fusions, the various chest drops that exist, whatever as a means to entice players to actually play PvP  - go ahead. Seperate the Great Hall entirely from it and sure as hell don't make content designed aound people having anything in the great hall. If people want to do PvP fine - but stop trying to force it on people by making PvE content dependent on it, especially cause of it's tendency to break or become a problem. And frankly - your PvE content is better and more interesting when you don't screw things up or overthink them.

Between this, the change to event scoring with the addition of Mythical artifacts (unless I missed that being rectified to the old scores and Mythical is now more points than Legendary was before their addition), and really a lot of within teh time frame of, and related to, teh whole 4th anniversary thing - this has been pretty damn bad. The last couple months has felt like the game is being run by and/or designed by greedy amateurs. And you've shown in the past your better than that nonsense. Now, you wanna keep this current track - go ahead, your gonna run the game in to the ground like I've seen others do, some to actual graves, some still barely sucking in breath (usually supported by a companies other projects). Otherwise - pull your head out, listen to the community (and maybe start rolling out some easy events to get champions - and I mena a noob with almost no resources and money can do them easy or straight up 7 day login ones to try and buyback some goodwill), and stop with this stupid amateur hour crap. 

It is bad as it is, that only a selected few can access the live arena. My secondary account which I hardly play has access and my main not. 

That about the people who play a lot in the Arena gets access. 

But the Hydra "bugfix" is absolut nonsens. Once again it was not properly tested. Liki most of the Times Plarium implements something. 

Miracle heal cannot help you there. 

Hydra is difficult as it is.

Teela Goremane just got a nerf to be a good Hydra Champ - now useless

Nekmo Thar was even a guaranteed Champ - now useless

I could go on and on.

Plaesa whatch the videos from Nub Raids and HH Gaming on this Topic. They explain it in torough detail.

Just read it on Discord (Farbstoff)

Plarium News

Hi everyone! We would like to address the recent Hydra changes.
The fix in the 7.0.0 update corrected a long-standing bug, in which "Almighty Decay [P]" destroyed the incorrect % of HP. The formula was fixed and now the Passive works as initially intended.
However, seeing how this change has negatively impacted the already established team compositions and Hydra-dedicated healing Сhampions, we made a decision to roll back this fix and update the description of "Almighty Decay [P]" so it can accurately represent a Passive's mechanic.
These changes will be implemented in the nearest future, and we will notify you once we have more details. 

Привет д дру.

Why i dont have live arena? And i cant download 7.0.0 

i

Beta right now, so limited invites. 

As for why you can't download the game: it could be a myriad of issues, including updating your NET framework to 6.0.14, which others in this thread: https://plarium.com/forum/en/comment/topic_1639800/ ran into as a problem. 

thanks for fixing the hydra issue. :)
