I see the claim that mobs just group up around you/circle around you alot, however, in all my runs, I do not remember that ever happening. I play every tank with the goal of keeping everything infront and that is what I do. I also only have to move to dodge AoEs, at which point I'm back and the pack hasn't move that much.

With this in mind, I want to make the claim that mobs circling you isn't a product of the mob A.I. but more of a player skill level. I tanked The Dead Ends today as PLD and had no issues keeping everything infront and I do not remember a dungeon where it was the case where I couldn't, feel free to name any, I have tanked alot of dungeons in my time.

So really, I want to know, how do people who always have mobs encircling them do the pull? When you get to the last pack do you just pull them to you and stand still? Do you do what I do and run through them so that they are all on one side? There might be other cases I am not considering but that is the only point at which I can think of where the difference would be.
