Biggest pet peeves when it comes to dungeon runs?

[Caurcas]

Yeah, no. That's not a good tactic at all, You risk pulling mobs unexpectedly to the tank or even worse, having said mob attack the healer. How about creating a macro before you dungeon dive? I've played DPS since, well since FF11...what you're not gonna do is pull more mobs to an unsuspecting tank, that's bad tactic all around.

I am doing that as a healer, and a decently experienced at that, a mob or two hitting me while moving them to the tank isn't a big deal. I also find it's a pretty good way to build confidence in tanks by pushing them to go beyond their comfort zone and to better prepare them for endgame norms.
