My only real issue with people in the game I've noticed somewhat regularly is how extremely unreceptive people are to advice, sometimes they even get aggressive or other people get angry on their behalf because someone dared to try and help.
It doesn't matter how much I go out of my way to sound as nice as possible it's almost always met with either being ignored or someone getting mad.
And I've definitely noticed it getting a bit worse recently.

People trying to help you is not a personal attack.
And if someone is standing in front of the boss and keeps getting killed by the tank buster someone explaining it to them is not harassment or shaming...
Some people are definitely way too touchy to the point that even just offering advice is seen as '' telling people how to play '' in a toxic sense.
And I mean if someone at level 80 is playing SAM and is standing in front of the boss dying repeatedly and not doing any of their positionals then I think you're the bad person for not helping them, but it's treated like the opposite.

I dunno why it's really bizarre but this is like when the toxicity comes out in my experience, everyone's all nice but the moment you try and help and it has anything to do with anything gameplay related people flip out.
