PvE is a joke, come on.
What are you basing this meaningless statement on? More people play pvp than raids, so the only arbitrary yet factual information is against your little linear corridor filled with scripted dummies.
Current MM is incredibly fun to play in pvp, and that's my opinion, yes. I expect heavy changes to alpha MM in few areas to become enjoyable, the priorities fluid, and the mechanics overall interesting.
In my opinion, this would be a good start
-removing marked debuff
-kill shot back, its hp % range determined by vulnerability stack
-casting time of aimed shot to 2,5 or 3 seconds with increased damage
-adding passive regeneration back, or lowering exhilaration cd significantly
-2 charges on turtle with 4 second duration each charge
-greater emphasis on arcane shot focus regeneration, slower baseline focus regeneration, perhaps a talent to switch
-arcane shot renamed and changed to a physical shot, maybe a talent to bring arcane shot back
