My worst grievance with tanks on Dawnslayer is when they pull her out of the choking cloud AWAY from the group; as in, they place the cloud between themselves and the ranged DPS/healers. Pull to the side, or pull towards the group. I'd rather backpedal a few feet than shuffle around the cloud o' obscurement.

I know that, at least for me, it may take a few steps around in order to ensure that all mobs are in front of me (the tank), from where I can block/parry/dodge incoming attacks. However, once they're all fairly well established, yes, for the love of god, stand still. Also a nice idea on the Asira fight of you are using a hunter as a silence shield, which I have done numerous times. It's not an arena fight...you don't need to constantly be twitching around like you're on a Red Bull binge.

I'm guilty of jittering. I do a lot of pvp as ret, and also typically dps as ret. From pvp, I've picked up the habit of being constantly in motion; I feel weird when I just stand there in one spot for too long. So when I occasionally slap on a board and go prot, I have to consciously restrain myself to only move when the mechanics of the fight absolutely demand it.

@Hondahatch77: Oh yeah, forgot to mention the "stand behind the big, fat, tauren hunter" tip myself.

I'm half-tempted to make a "Get behind me, doctor!" /yell macro just for the Dawnslayer fight.

I have learned in Cata to not be that tank who hops and spins like a blue heeler at dinner time.

I had this problem when running as a feral kitty in lowbie dungeons. I know, I know, lowbie dungeons aren't that important, just do DPS. Problem is, those are the training grounds for future heroic and raiding tanks; if they can't do something as simple as standing still while tanking a (relatively) very easy boss, how will they fair in LFR, etc?

I don't mind moving to get everything just right. But I had a tank who was quite literally tanking around in a circle that was completely unnecessary. Was just sad.
