And that is where the tanks are now. There isn't much difference in their performance from a DPS standpoint and they all have similar mitigation kits. They all play differently, their short cooldowns all operate differently, even their 'I'm not dying' buttons are different. Everything that needs to be the same is the same. If they need to homogonise some aspects of the tank role to ensure they have the basic kit, then so be it, however, that doesn't mean all tanks are the same.
