Okay, so I wanna kinda explain how my thought process goes as a tank. The first 1-2 runs of a dungeon I take kinda slowly so I can learn which mobs hit the hardest and what packs I can safely pull (as well as commit all that information to memory and/or Notepad). However, once I'm pretty comfortable with the dungeon, I start to increase the amount of packs I pull (although I will slow down a bit in case of a wipe or the healer struggling to keep me from dying).
In a way, the team should at least try to communicate and facilitate the run going smoothly.
