A few things:
Mesmerize: Sleep only lasts 4 seconds by default in PvP. So the sleep set is only good for the bonuses. Just an FYI. I would otherwise suggest slotting it as an attack.
You can either get rid of, or remove a few slots in, TK. In PvP, it only has a 10 second duration (or maybe its 15... i forget, but it's short and finite as opposed to in PvE). You can probably use one of those slots in Tactics to get a damage bonus, which seems to be what you're going for with your slotting.
In Stamina, as long as you're using a Performance Shifter proc, put in 2 more P.S. IOs so you can get some decent set bonuses.
Hurricane: Just use one full set of one of the sets you have in there: You might as well, since you're not stacking any bonuses. True, you get a better amount of -ToHit, but thanks to Diminishing Returns it probably won't help much. I'd also try to add some KB in there to help knock away your foes. KB, while any decent PvPer will have mitigation against it, is great against anyone or anything that doesn't have resist against it.
Try to fit freezing rain into your build. True, it won't slow anyone down... but if you cast it at your feet, it'll be another tool you can use to keep stalkers off your butt while you take care of other matters.
That's all that jumps out at me... looks fairly solid otherwise.
-STEELE =)
Allied to all sides so that no matter what, I'll come out on top!
Oh, and Crimson demands you play this arc-> Twisted Knives (MA Arc #397769)
