I've been 2h frost dps ever since I started raiding, i'm running a specc that I just tailored for my own needs and it's working great. In 25m raids i'm always in the top 5.
You can argue that UA > Lichborne anytime you want but I'm just too lazy to work in another frost rune into my rotations so it's a nice filler

Can't wait for the patch tbh.
