On severe reaction, I have actually come to like this one. It pushes just far enough to be out of small mobs reach, while still having them in range of icy veins. This is very useful at least when soloing. It doesnt push far enough to make mobs miss my AOEs either.
Agreed the effect is still small and too infrequent to be counted on, but not all bad at least! ;)
I have to pick something to advance the feat line and other options are not exactly splendid either

I respecced a bit last night. Alacrity had to go now that I have spelltwisting and better recovery. Since I find myself using ray of frost quite a bit against bosses/dragons I moved the feat points into glacial movement for extra cold stack aswell as the option for better orb of imposition if I need more control (otherwise using chilling precence and storm spell for damage. I also maxed my crit chance now with the heroic feats aswell as maxed cha.
All in all I think the change will give me better damage w-o sacrificing much control.
Cheers
