I can get that and really shouldn’t happen but this is the issue with holy trinity games and especially when Blizzard does it. They stack so much responsibility onto those two roles, make less of them to be picked from and are often the first things to fiddle with (Nerf or otherwise) in an attempt to fix the game, perfect example is dropping to 1tank.
So tanks and supports are tired of their fun coming with far more responsibilities and the moment it becomes a tad more enjoyable the incredibly limited hero pool gets hit by nerf after nerf which usually come from complaints from dps players some how not having fun with said tank or support.
People still cry about rez. A single rez, with a 30second CD that places Mercy almost at a stand still. Yes, really good Mercy places can make it so it isn’t so limiting but come on, that isn’t the common player.
So yes, the DPS players didn’t really do anything and shouldn’t be argued with as if they had but not really helping when there are just constant complaints about abilities that make it slightly more annoying to get a bunch of kills.
