Gemming and enchanting is a little jacked. Put a 10 dodge/15 stam in the red slot on your belt, everything else should be 30 stamina. 10 stats gems are bad for warriors. Cape needs 225 armor enchant, gloves need either 18 stam or 240 armor kits (2% threat is nothing and parry is bad), and I would switch blade ward for blood draining or mongoose.
Also, take the 2 points from Cruelty and put them in Imp Disciplines, to magnify the effect of your shield wall glyph. Switch sunder glyph for devastate, and blocking for either last stand or taunt, depending on fight (carry stacks of glyphs on you). Drop glyph of bloodrage for glyph of command.
That gets your gear and spec in line. Any questions about rotation? Priority system for a prot warrior is:
Shield Slam (normal and procs) > Revenge > Devastate/Shockwave (if you have 2pc T10), with heroic strike spammed when you have 40+ rage.
