That's not my experience at all. Before role queue it was common to get yelled at for not choosing a class that would fit into 2-2-2 meta. I quit around the time role queue came out so maybe it has improved?
That has less to do with anything the game/community has specifically done and more to do with people always looking for “easy” answers to the problems they see — blame the loss on balance, on team members, on lack of minmaxing, on luck, on people not doing their jobs, etc.
And they yell those answers at you because you’re playing a team game where they depend on your success for their success.
In the end, you need a thick skin to play effectively and actually get better, to pierce through the noise and rabble
And more importantly, at lower levels of play the meta is generally far less important than fundamental mechanics in terms of actually winning consistently.
