I think Precision Strikes and Massive Criticals are overrated, at least for Warriors. Save your character and retrain your skills. You'll find your DPS will be higher following Duel + Heavy Hand + Flurry. (Note that Flurry has to be active for it to raise your DPS). At level 24 or so, maxing out PS + MC gets me about 4.5 DPS for 12 skill points. I can max out HH for 6 and get 5.3ish DPS.
As you get to be higher level you may start to have room for all 5 skills, but you're still probably better off with Magical Training and Bloodlust for breaking stun.
