@ Grak.

I've tanked DK, Bear (ok, lowbie bear, but the basic mechanics are still there), and Paladin, and warrior AE tanking isn't worse, it's just more... fiddly. Paladins just drop consec on CD, swinging the hammer of righteousness and keeping HS up, all the same things they do in a single-target situation. DK have to hit a few separate keys, but they've got a pretty decent array of abilities, from DnD, to pestilenced diseases, to blood boil, covering any sort of AE situation. Druids have swipe and glyphed maul, which, while not complicated, are practical and with no CD but the GCD on swipe, entirely spammable.

Warriors have the threat, they just need to rotate TC, SW, and talented Revenge, using cleave on melee swings and keeping shield block up and tab-target. The threat is there if you want to fiddle around and do it. The one thing a warrior lacks is something which is less timing-dependent. 6 second TC cooldown means that if you didn't catch a few mobs in that area when you hit the key, they're loose until you single-target hit them down, basically. It works, it's just... fiddly. In the meanwhile, in live, every other tank has some sort of ability designed to prevent timing the ability a little slowly from causing problems. No, simply walking through consec won't make the mob glued to you, but it gets them looking at you first, buys you plenty of time to adjust, same with DnD, and swipe can be hit next GCD.

Again, I've made my peace with it (that and our last-place threat from range). Our superior mobility, our stuns, our anti-caster mechanics, and very capable rack of cooldowns make up for slightly fiddly AE methods.
