I view Watchman as a Feral Druid and Combat as more of a DW-Frost DK. Yet to try Watchman as I've played Combat all the way but the only bleed I have is Cauterize and for the most part I don't put it up unless I'm moving away from something, feel more like Deep Wounds on Use rather than on crit.
But yes, the rotation is indeed deep.
General Rotation including Inspiration(Or Transcendance/Zen if you're not the only Sentinel and you've sorted out who's buffing and what-not) and Cyclone Slash/Force Sweep
Inspiration > Master Strike(If Precision is Up) > Dispatch(If Precision is Up) > Zealous Strike(If Focus>1) > Strike(If Focus>1) > Blade Rush(If Combat Trance is Up) > Precision Slash > Master Strike > Pommel Strike > Dispatch > Cyclone Slash (If Target =>3) > Force Sweep(If Target =>3 AND Stunnable) Blade Rush > Zealous Strike(If Focus>5) > Strike
I *think" that's as close to a rotation list as I can think up, but without accurate tooltips (torhead.com only displays level 10 talentable values and some wrong values (master Strike))

-Two points in the AoE reduction talent can be put into any of the other 2-point talents, but as you shouldn't be taking full on melee swings Rebuke is worthless, and the others are clearly PvP talents-
