I think IR is slightly better for WAR since wrath stacks also increase crit%, but after nerf? Meh. I got pretty much the same set up, except I don't have provoke yet (bad tank, bad!) but will tonight. Which means I've got to decide whether to replace second wind or IR. I have SW macro'd with Thrill of Battle for a little extra bump, but it's not much of a heal outside of that. Probably replace IR, not sure yet, though.
