Play a Pally if you want to tank great (as good or better than WAR), and be able to hold aggro like a turd holds stank. Not to mention heal, stun, blind, etc etc. Seriously...I play a WAR in a tier 7-9 raiding guild and Pallys are overpowered atm and are the way to go if you enjoy tanking.
You sir, may have a warrior in that tier, however, you quite obviously have never played a pally if you think our aggro is 'easy'... we have to be extremely spammy to keep up. Additionally, our mitigation is the lowest of all tanks. Warrior mitigation is the highest, and SK mitigation is also better.
Pally is fun, don't get me wrong, I love my paladin. But they are anything but 'easy'.
Also ignore the guy who said taunt spam, taunt spam is bad very bad. Taunt gives you the highest persons agro on the list +1 so if its beating on you it only gives 1 agro. Its mainly used as a tool to peel a mob off a player
And you SHOULD keep hitting it...if you have highest aggro why not keep hitting it for another +1 every time it refreshes?
It doesn't ALWAYS peel a mob off of someone either. It's best to just mash it and accumulate additional aggro in my opinion. I don't have trouble holding aggro on my warrior (46), paladin (63), or SK (57) using this method.
Also...as someone linked above - invest some time in getting those Furymail gloves. +aggression mods make a BIG difference from what I've seen. Those are ridiculously easy to get and should help you quite a bit with holding aggro. The stats and AC are pretty weak, but AC is easy to get elsewhere.
Advanced Anatomy is THE agro AA for warriors.
Ambidexterity is prolly the second best agro AA.

So it doesn't add one right? It just puts you one ahead of second place?
