As a tank the first thing I do is ask if anyone hasn't done the dungeon before or if it's my first time in the dungeon I'll let folks know it is and ask what the kill priority on trash mobs is. Then when I hit a boss I'll either give a cliffs notes version of what to expect or ask what to expect. It doesn't take long to do and if people are an asshole about it I quit the dungeon. Woot for Paladin instant queue.

*Note I'm only up to Cutters Cry. I plan on researching the Hard mode fights.
