I've been wondering the same thing, what happened? It's obvious that they took out the bots, but there appears to be other things they changed. I use to farm G4, but now I have to super selective less I lose my spot. 

Really hoping they revert it back. Not sure why they changed it.

I have two accounts, one I bought some gems/energy, one completely F2P.  The paid acct is on day 134, has been in G4 for a while, and would sit right below plat most of the time.  I'd get hit 40 times (exactly 40) after each reset, and then nothing but wins on defense til the next reset.  The only losses would be when I'd get pushed into plat, then I'd immediately get booted.

My F2P is 81 days old, has been in G4 since day 32ish after getting High Katun.  I was running a double boost with HK, Bloodpainter (4 stars and only 3 star ascended), Warmaiden (lvl 50), and Galek.  This team got pushed into G4 on defense in a matter of 2 days after getting HK.  Exact same pattern, 40 exact losses after reset, then nothing but wins.  

Exact...same...pattern.  But the teams I had on defense were miles away from each other.

The game is rigged, and they took out the rigging.  Check your battle log on defense.  I got attacked 53 times in 13 minutes tonight.  My P2W acct is back comfortably in G4, and likely belongs there.  My F2P never belonged there, and is struggling to get back to G4 each night.

Honestly...if I get 39 tokens per day, I shouldn't be allowed to be attacked more than 39 times.  Certainly not 53 times in 13 minutes.  And yes, I run a better F2P team now, with Skullcrown, HK, Tayrel, and Gorgorab.  It's not G4 worthy yet.  But...53 times in 13 minutes never happened to me in over 4 months of playing.  

It changed with the patch.  It's rigged.  And they changed it.  And they'll lie about it.  Because Plarium is despicable trash.  But just look at your log, you can see exactly what I'm talking about.

they have taken out the bot pages and changed something to kick out inactive accounts everyone is noticing the crazy change in terms of for example i could handle 250 000 to 275 000 teams but now as of 2hrs ago each refresh teams ranging from 300 000 to 375 000 - basically whatever was changed has turned G4 into a new plat level with the teams im finding.

my team arbiter, rhaz, ithos & candraphon at 190 000 but could match it with teams up 275 00 consistently but 8 refreshes not 1 team under 300 000 is a joke 

i see same problem. is again like few months ago when win 5time/day is impossible iven if a roll 20 times pple are unbeatable, and i lose vs. ppl in half my power (i have over 300 speed, arbiter on lead) and not start turn vs.ppl with no lead speed boost... how?

and die in first rund...

yup, still waiting for a gm/admin info about it :D They wanna bring CvsC in 4.40 so maybeeee ... they will rework theyr system also. Any1 tryed contacting them(staff) over discord ?!

It is also my impression that it gets more and more difficult in arena.  It seems to be that me arena team is not good enough anymore for Gold Tier 4. 

So if this trend continues than more and more team will drop the Tier ladder and it will get even more difficult for newer plays to push into silver and beyond.

inactive accounts are still there, I checked. I had 1 champion against me, it was impossible to get through it looked like a tank. So I wanted to send an email via plarium to his account, it turned out that his account had been deleted. So inactive accounts are definitely still in it.

I've  been  struggling  for  almost  a  week  now  and  more  today.  Was  G4  for  months  and  now  G2.  i  am  middle  game  player  i  think  and  have  bunch  of  leggos  and  F2P!!  how  can  my  team  at  153k  points  get  defeated  by  99k?!!!  In  1st  round????!!!  I  saw  few  times  that  my  champs  have  no  gear  and  one  time  my  team  power  went  down  to  35k!!!  Any  chance  that  the  gears  are  remove  during  arena  fight????  

same thing here but iv notoced over last month, comfortable in gold 4 now im in silver/gold 1 if im lucky, has me contemplating quitting

I  sought  help  and  went  from  over  1600  to  under  1300  which  is  bronze.  I  just  did  climb  up  to  silver  again.  I  am  looking  forward  to  another  20  defensive  losses  in  a  row.  If  i  were  you  i  would  NOT  seek  support  from  Plarium.  Just  my  opinion.  Still  a  fun  game  but  i  am  not  going  to  be  able  to  progress  like  the  older  players.  

Yea I have noticed the same thing arena is completely borked. I will never get my great hall abilities leveled up

whales !!!
