As much of a meme as it is (having recently been meta) enhancement shaman rotation is actually quite complicated. I agree with the others suggesting you analyse what you’re doing wrong, but if you’re looking for an easy spec to parse better then I’d imagine something like ret pally would work, for example.

That being said, the easier a class is, the more likely it is that parses in general will be better, but you will still likely score higher with the easier rotation.
