Warrior is more enjoyable to me tanking in Ulduar, but we are comically outclassed. Paladins are superior as tanks in this current raid content. There is maybe room for 1 warrior who is geared enough to both OT and play fury.
Play a Paladin. Holy/port is 3000x better than Prot/fury. Ret also becomes busted in ICC because of their tier, on top of a buff they got which will amplify the brokenness they use to have in ICC.
Three top of the line specs for Paladin vs. 2 Mid tier specs for warrior.
