Enhance isn't doing well on it.
(apologies if I misunderstood your point, it may be worth rephrasing it)

I haven't seen a simC result with enhance in the upper quarter, here is the current one.

Enhancer is always low, and unlike a lot of other classes doesn't have another higher performing spec it can switch to.
Could you link the simmed result you are talking about please.
Not sure what you referring to here, could you link logs where enhance "outperform the majority of the rest"?
Again could you link some logs that could cause Blizz to think about nerfing enhance?
Well said, we can only talk about what has been logged so far. (so please provide links otherwise it just looks like opinion)
