To be fair tank dps is very much not what threads like this make it out to be. Gunbreaker is the best, by a wide margin. Right now Warrior is second, Dark is third, and Paladin is last. HOWEVER, the gap between Warrior and Paladin is smaller than the gap between Gunbreaker and Warrior. In reality Paladin dps is really not much lower than two of the other tanks, it is very marginal. Just all of them not named Gunbreaker suck compared to Gunbreaker. Breaker has the harder rotation though so I guess that's how Squeenix justifies it.
