Feral 3.3.5 Tank
Feral tank druid is a good enough tank in this expansion, but with the Icecrown Citadel debuff (Chill of the Throne) you get -20% dodge which is the only avoidance for druids, but you have a lot of health. As a feral druid you have your own raid supports which is useful, druid is probably the 3rd tank after death...
