As a student in game development, I've seen a great amount of player base lost due to unfixable balancing issues because nerfs and buffs are constantly being applied. You know your game best, and sometimes you got to not listen to most of these people complaining. Either they aren't looking into alternative counters, or just they just plain suck at your game. I understand you gotta respect your players, but the game isn't gonna fall into everyone's favor.
