I dropped all the way to Library. Arena will never change so long as players think X creature is the best. Even with a nerf to ProceRat and a buff to other Uniques, Arena will be the same. Championship will never be fun if there is no incentive to play after the 200 trophy drop from high score.
Ludia has made PvP something that is central of the game but also the worst part of the game. I wouldn’t even care for any of the 3 to 4 variants of PvP if not for alliance missions.
Blue Season has made me just throw matches just to have fun dropping and watching the progression of the same 10 to 20 creatures at different levels of boosting. Looking at how much investment there are in the current ProceRat and Thora meta, a nerf to both (I dun use either) would result in a whinefest.
Variety can only happen if Ludia is willing to let go of boosts or make them 100%reassignable.
I would be stuck in a losing cycle if not for Boosts 2.0 because I invested in Utarinex and Dilocherius. Imagine if ProceRat is nerfed, how many players would quit in anger since their major investment is now useless. I personally dun care since I have a diverse team and can take a short term loss for a long term gain.
