But they did address that a bit by re-adding open queue, also flex queue helps a little bit if say one day you wouldn't mind playing tank and then another day you just wanna go strictly dps. But I guess it should be fairly straightforward to expect people playing first person shooters to want to play mostly damage characters, and there's probably no easy queue-based fix for that.

Yeah, but by the time they addressed it, it has already given everyone many, many repeated large reasons to move on from the game.

The worst part is/was (unsure if this has changed) that you are hard locked into specific hero categories even if you are queued as a full premade. Even when you are with a full team that is OK with swapping, you can't swap roles as needed. Incidentally, I played dps junkrat back when it was categorised as a defence hero. And the categories were decided and changed by Blizzard - Junkrat might have been the only defense hero I'd be willing to play, and now the only offense hero since they recategorised him - I would rather heal than play mccree, but there you have it

Open queue is plagued with stacks of people queueing as tank/support to get easy wins. So one side rolls over the other in the majority of games.
