Eh, there isn't much more to say that'd be worth starting a new thread. Yes, Coldrage + Glacial Blade (from AV) with Frost Oil is pretty much what you'd want as a rogue. You really don't need to be doing lots of melee damage -- the goal is to freeze him, then use good weapons for globs, and repeat.

I just looked through all daggers, fists, swords, maces on allakhazam (my eyes are bleeding) and there don't seem to be any 1h weapons that give static +frost damage.
The problem with Glacial Blade is that you need to be revered in AV and it's horde only.
So that leaves alliance with a whooping lvl 40 dagger. *yay*
Not that horde has shamans for that fight anyway. ;)


***edit
Aah, one more thing. Does Icy Chill also count as a frost spell?
