There's nothing wrong with tanks and they certainly dont need to be made overly elaborate because one person is bored.

The only thing they have still left to do is give Paladin a similar buff that they already gave Warriors. Specifically one that adresses the concern of us only being able to use Flash to keep AoE hate (because Circle of Scorn is useless on such a long recast, make it 2.5 seconds instead of 25 seconds).
