I found Hibernate really useful for tanking higher levels than you would normally.
It's a good power when you get in over your depth or just want a little hit point boost when Hoarfrost is not available.
@Unthing ... Mostly on Union.
aye, sometimes you hit an unlucky streak and then youre glad hibernate is there to save your butt
"god, how many devs did hami have to sleep with to get ED?"
Total Cat @Stagefright
also you meet stuff with high acc like those three legged drone type things which i hate cos they hit quite often and they don't fall on the ice patch which annoys me even more!
with hoarfrost and hibernate and greens and purples fighting +2's drone type things was umm ... pretty challenging 
Hibernate is also a god-like power in PvP. You'll be getting screams of "[censored] imba" a lot.
You need Hoarfrost. 6 slot it and use it often. You probably want hibernate too, but you might not need so many slots. Put Taunt duration enhancments into CE and Taunt so that you don't loose your agro to quickly.
I really should do something about this signature.

Tell me about it. My eyes hurt after using it. What language! 
Hi all
Almost L32 when I can get hibernate.
Was thinking of getting it cus it sounded pretty cool (no pun intended).
However just respec'd to be more of a tank and I dont find I run out of hp very much and if I do get close I have hoarfrost.
So what I am wondering is does anyone find much of a need for both hoarfrost and hibernate, or would I really only
need the 1 ?
Thanks for any thoughts
