Honestly, most of the drama in the game comes from expectations.
I have no problem if I get in a group, say I’m rusty or working through it and then they kick me? Fine. Best to know up front, right?
Vs coming in, no one says a word, tank starts wandering around, pulling too many mobs, messing up the boss, and THEN “Oh, sorry”. If we’d known you weren’t up to speed BEFORE, we could have given the 2 sentence boss fight tips or “hey, go left here” advice.
But get the expectations right.
