It's pretty important you make sure to use all the GCDs during BW on Kill Command, Glaive Toss and Arcane Shot. You'll also want to try and fit two KCs in one BW. Same applies, and even more so, if you have the T16 4-piece bonus.
And yeah, don't bother with Haste/Mastery until you're much more geared.
