If you're so unconfident in your answer that you need to put a caveat on it that people should ignore you until it's confirmed, maybe you shouldn't be posting. Just a thought.
Note: Take everything I wrote here with a grain of salt, unless someone else confirms it.
Abyssal rune ? I'm sorry, but you are wasting a slot there. Even the brewfest +crit trinket (copy of pocketwatch) would be better. You are over the 401 haste softcap, so crit should be much, much better than haste for you.
Get rid of Owkin Frenzy. It is useless. I don't have any points on Intensity, and neither should you. In your case, Dreamstate _should_ be better (do the math, please).
Also, you should do the math and see if 2 more points on Moonglow wouldn't benefit you even more.
And get rid of ImpMF. Really not worth it. better to put those 2 points somewhere else. There is some math on this thread to prove it.
