Here's the thing. Everything dungeon in this game really plays the same way. There are a few exceptions (for example, if an enemy is going to stun me as the tank, I let the healer know I'm going to be eating a lot of avoidable shit), but generally speaking, every dungeon can be done completely blind in the same way: pull everything to the door, AOE it, kill boss, repeat.

You don't need any experience in that dungeon to be able to do this, so being new isn't a valid excuse.
