Worst I've run into at earlier levels are level synced dps that like to push the limits of what I can do as a (admittedly) brand new tank. It's a little stressful in the moment, but 3/3 comms so I must've done ok. There's a bit of rage thrown at my high level heal game, but I've had bad days and good days, and 'typically' people are pretty understanding. It should be noted that I generally don't play with folks who obnoxiously demand speed runs... While I'm not opposed to speed runs perse, demanding ppl are their own red flag, IMO.
