Survival: I believe there will be a point of too much Multistrike in W.O.D. After some testing on beta, I was able to get my Multistrike up to about 45% at lvl 92. At this point, the ES "spamminess" felt close to that of what its like on live with our 4-piece set bonus (lets not even get into what it was like having both the 4-piece and 45% Multistrike felt like). We don't want to get to a point where we are getting LnL procs too quickly. My prediction is that anywhere from 50%-60% will be comfortable for a lot of Survival Hunters (maybe a little more, someone will do the math once we get closer to launch), so once we can get to that point at level 100, will we start to look for other stats, possibly and little haste, but will probably go for Crit again.
Marksmanship: With our baseline Crit, and the way Rapid fire works with Careful Aim now, I don't think we are going to want too much external Crit off the bat. Or there will be a mathed out soft cap with will a good point to reach. I predict haste will our most important stat. It will help with Aim Shot cast times and focus regeneration.
Beast Mastery: Not too sure, I don't play too much BM. Looks like Mastery most likely. More pet damage never hurt nobody
I haven't spent to much time with MM or surv yet but as for BM I've been getting better results with crit over mastery. As for what little time I did spend with MM I can say I was really unimpressed with mastery
