As a tank, I love it when healers or dps pull. In my experience the one's that do are usually good at dealing damage. I actually get excited and think "Yes!, this is going to be a good dungeon." I don't throw my hands up in the air and cry like a baby. I just hit one button and now they're all on me. Then we precede to annihilate the dungeon. NOT because we are in some great hurry like the nonsense some spew, but because it's fun and large packs are the only way to make full use of your tool kit in these dungeons.
