So I went with more balanced stats and they turned out to be pretty much spot on as shown in the reforge plots:

Crit 9217
Haste 3445
Mastery 7724
Versatility 247
Funny enough - the worst weight of above stats is currently....INT

Standard TV build still sims 20k higher for me, but in real fights it is much, much harder to approach the simmed max with it. Ice floes turns out to be quite insignificant when FBs are 1.1s under IV, so movement is a bitch. Meanwhile an ice floed GS allows to cover quite some distance. Another bonus is splitting ice 24/7.
Now its time to test it on the PTR.
EDIT: as expected, with the removal of 8% haste on PTR the spec is pretty much dead. If not tuned much higher, it will be rock bottom of the lists on everything except 2 target stacked cleave.
