So I main PLD I usually tank unless a friend or FC/LS mate wants to tank, but in this case I went in to 50/60 rolo with my RDM and my in game wife went healer(WHM). So a little but into the dungeon she gets a lag spike and everything freezes up, she hits bene cause she's worried the dude was gonna die while she was lagging and the PLD immediately calls her out and starts going off on her and calls her a ****y healer, I stood up for her saying I've known her for 3 years and she's anything but a ****y healer then he called me a simpleton and that we were just casuals. Ironically earlier he had forgot to apply any oath and I pulled aggro but I didn't call him out on him I just thought "meh its DF", I did bring it up after he went on his rant though and he went on about how he was allowed to make mistakes and she wasn't. Should I just try to tank as often as possible to avoid these kinds of people?
