The reason warrior tanks work so well in raids is due to the other things they can do. They are far and away the most mobile tanking class being able to very quickly move around as needed. They have very good aoe threat and yet again their aoe threat is mobile. Once a DK drops death and decay, good luck moving around for the next while. If they are a bit slow on a pack of adds, they can AoE taunt them until they build some aggro. They have more silences than any other tank, more stuns than any other tank, provide the best melee AP reduction debuff, the best raid health buff, stack the sunder debuff on the boss and if you are doing the farm runs no other tank can come close to the rate of pulls that a warrior can manage.
Yes you can make a raid with all the same capabilities without a warrior MT but you pretty much have to build the raid around not having a warrior. The only weakness of the warrior is the relatively small number of cooldowns but with so many healer cooldowns available now that is a lot easier to manage. If the mitigation is similar, the cooldowns are close enough and the threat is similar then it makes a hell of a lot of sense to use the tank that can stack a ton of buffs and debuffs while also having the greatest mobility, most taunts, fastest pulls, most interrupts etc. etc. etc. The reason so many guilds use warrior MTs is nothing to do with their damage reduction which is so close to the other tanks that it makes no difference. It is because they are just simply better at everything else that you will want your tank to do.
