I really like Enhance shaman in MoP remix, I play really similar to your build but I play with thorim's invocation instead of elemental spirits. the amount of times you roll bad elemental wolves is frustrating and Thorim's absolutely cranks when you proc Ascendance.
I absolutely love windfury and enhance shaman, the only reason i was not playing it much is that i'm not really fond of dual weapon, i wish for the next expansion they bring back 2handed enhance, it would be so bonkers! Having said that, it's still satisfying to play.Cheers m8, have a nice day!
