for AoE, trip tclap -> sw -> tclap, it should help a lot with initial threat.
For single target it needs to be a priority.
For threat: SS -> rev -> sw -> devastate
If you want to do more dps, then switch rev and SS. Using shield block at the begining for more spike threat is also a very smart move.
As far as threat goes, everything looks in order. Your spec/glpyhs are correct, expertise/hit levels are more than acceptable, though maybe eat expertise food during raids. Make sure your HS uptime is high, it needs to be 90%+ if at all possible.
