Guild Wars 2. I stopped playing because it seemed like whenever a competent healer/supporting role showed up, people would start bitching about "why can't my DPS do that?" or "why do we need a dedicated healer and/or support for end-game content?"

My favorite elite spec for a long time was chronomancer because it was basically the gold standard for what made a good support in the game. Then, instead of looking for other classes with support abilities that could be buffed to Chrono's level, Anet trashed it because people kept bitching about it being too hard, "boring" (because apparently mindlessly whacking something with a stick isn't boring), being too powerful (it was literally one of the only viable supporting roles in the game), etc.

Anet is (or at least was) really bad at balancing the game properly. I'm not sure their balance team actually plays the game, or even communicates with each other on what changes they're making because they have a tendency to stack nerfs or buffs.

The community as well tends to want every class to be good at everything at the same time. Like, don't get me wrong, the ability to respec from a supporty role into a DPS without switching characters is awesome; but if you're rolling DPS then you're not gonna be able to shit out boons like a support can.

It sucks because I love the overall atmosphere of guild wars, but watching my absolute favorite spec get completely gutted because of bitchy, whiny players that were basically the guild wars equivalents of "I'd be high rank if it weren't for my shitty teammates" was heartbreaking.
