As a Bear Tank, I am aiming for 42k-47k unbuffed HP., as of this post, I'm at 37k or so In Bear form. It's a hard road to do with also trying to keep up your dodge % cap ( lil over 6%), Expertise rating, & ArP and Hit cap ( 8% for bears) for threat, and dont forget to spam Agility, which truely helps out in all phases of bear tanking.. Im guild OT, in a pinch, but main role is Treekin, tank spec is for my own personal enjoyment, and Im still building my heal gear. we have a pally and warrior MT's, I guess you can say. We are working all 10's and 25's ( including ulduar ). It's tough to try to keep caps in all area's at max, while also inter-lacing ( upgrading) gear as we move along with progession.
