taking down Titan as tank

[Kumabear76]

Heres what I've been using - Defiance, Provoke, Wrath I-V, Maim, Skull Skunder, Butchers Block, Inner Beast, Blood Bath - anything missing?

Never pull with Provoke. All provoke does is put you at the top of all current aggro pools by 1 point. If you pull with Provoke, that sets your current aggro at all of 1. On the other hand, pulling with Tomahawk or Overpower places you significantly higher.

Not much to add other than what's already been said. Face titan away from the party and trust in your DPS and healers. As a tank, your job is simply to stand there and get hit while the DPS's burn him down.

EDIT: I'm curious if you're just listing the skills you used or is that your rotation? If it's your rotation, you're missing out on lots here. Skull sunder and Butcher's Block chain together with Heavy Swing to grant bonuses. I assume you know this or you couldn't build Wrath.
