To be clear, the reason I haven't quit yet is because the game does some things (namely, the animation and some of the character design) better than basically every other game on the market. It's just that my enthusiasm for the game is severely hamstrung by the developers' seeming incompetence (or forced negligence, in the case of executive meddling).
In terms of gameplay I don't consider any gacha game to be top tier, but I can't think of many games that are as blatantly broken as this one. If all you think about is whether or not you can progress, maybe it's not so bad, but given that it's a game with a significant emphasis on PvP and constantly has to resort to some really obscene restriction mechanics in PvE it's extremely obvious to me that they should have fixed a lot of this stuff a long time ago.
It's less "I fucking hate this game" (though I certainly will vocalize as much when I'm playing arena or GW) and more "this is weirdly disappointing". So many problems and they just won't address them. It's even more bizarre when you consider the things they did fix, yet for some reason fundamental issues like poison breaking the game and being countered with absurd restriction mechanics continue onward. I just don't understand it, man.
I just find her mechanics strangely deaf to the current state of the meta. To really work, curse should be stronger, she shouldn't be stuffed so hard by immunity, OR she should have extinction somewhere on her kit. As it is, against 90% of arena defense teams in champion she's entirely useless and in GW she's easily replaced by other units that are easier to gear up (since she needs effectiveness to do her job).
I don't know who's in charge of balance at this point but I am not liking the things they are doing.
