It doesn't - I forgot to cast Protect and I wasn't looking at chat with the tank spamming protect until he stopped at which I knew a kick was coming since he mentioned me pulling because I accidentally pulled trash before he stopped.

But it's hardly a reason for anyone to stop running the dungeon, it doesn't effect any person in the slightest. If I was doing an Ex Primal or Savage content, it would've been acceptable but Protect isn't going to be a question of life or death in roulette.
