I'm all for letting people watch cutscenes and waiting for that in dungeons but being new to a dungeon is no excuse to do single pulls. Trash mobs are the same in every dungeon and all you need to do is push your aoe buttons and occasionally push one of your mitigations. Get this tank = leader mentallity out of your head asap, leadership comes through competence, not titles. If someone else pulls for you and drags the mobs into you be glad you had to do even less and if they dont do that, tell them to start doing that. Taking over aggro as tank is an absolute joke and people dont just die to 1 or 2 auto attacks either.
