Does anyone have issue where a ton of versatility gear is dropping?
In the effort to increase my item level, so I can do heroics (i know I'm late to the game), all the higher level gear that drops has versatility, do BM hunters need versatility now or is this just bad luck?

So I've played WoW since start of legion and my dps feels so off. I'm doing about 350-500k a raid, but I see another bm hunter who does about 750k. I've used the rotation that icy-veins has suggested, but i'm still not doing well. I want to do a lot better. What can I do?

I have a lvl 104 MM hunter currently, with 7.1.5 I have heard BM is more viable. Should I A) switch my spec now for leveling B) keep MM for leveling but dump AP into BM artifact. 
If "A" what should my basic build look like?
 
THanks for the help!
