A New Kind of Tank
What? No tanking tree for Death Knights!
That's right, Blizzard is apparently trying to get away from a single tanking tree for the Death Knights, allowing them to spec however they want and still tank. Will it have the other tanks up in arms? Read Blizzards comments and decide for your self.
It's definitely a different approach than we've tried before.
But here's the problem with those existing tanking trees: not many warriors or paladins want to go into those protection trees, so there are a lot of 4-player groups out there wishing they could run an instance but unable to find a tank. And even if there were a lot of prot warriors and paladins, there is a math problem because a 5-player run needs 1 tank but a 25-player run doesn't need 5 tanks. A potential prot warrior might not see the point of taking up the shield knowing that some percentage of prot tanks will have to give up that role in order to get into the raid.
