It's an exaggeration, I think it's an extreme minority of people to the point that said people basically must exist only on patreon because I almost never ever see game balance suggestions here on itch.io.
Active? Eh, depends on how you define it. More active recently as I've tried to be heard.
Hatred? Strong word. Try frustrated.
Emotions? I'm emotional about a lot of things, particularly when I feel ignored. I've been the catalyst for changes in this game in the past (speed changes that made turn order more consistent largely stemmed from me btw) where aura dev had responded to me, as someone who bought the game I think I could've at least been respected enough to be communicated with. After so long of radio silence yes, I'm a bit less amicable.
Further, I paid for a game I liked, constant balance changes almost only ever in the negative has turned this in to a game I don't like, and would not have paid for. I bought Hollow Knight Voidheart cheaper than this.
I think the game balance is constantly made worse because they're made through the lens of the developer who knows everything and is an expert. They keep balancing the game negatively in the pursuit of challenge ignoring that the game already was challenging - they just had all the answers already. The game is being balanced around the most experienced players and the dev. I don't know how to tell you how absurd that is in ways I already haven't. 99/100 times if the dev is finding something too easy or lenient or strong in this game it's because they already have the solution, but they tweak stuff anyway, constantly narrowing down how strong we need to be to achieve something, how perfectly we needed to budget our money 20 days in advance, or even just limiting the strategies available down to having 1 solution for the boss.
