I am a new player and I don't know much about hydra and its changes but some of these comments are saying that these changes are good and a few of them are disagreeing. so, I request you to tell me about it in detail.

There's no disagreement on whether or not the changes are good. The only disagreement is on whether they are enough.

Personally I think they are fine. I'd say Hydra is now just about exactly where it should be.

I think any easier might trivialize things a bit too much, though I'm fine with more nerfs to Normal/Hard. 

Head respawn RNG can still be a bit frustrating at times, but other than that I'm pretty happy with it. 

Speaking of changes - does anyone have the new stats? Looks like bobo's list is still from the previous season.
