Snowcloak in 50/60/70. I hate it. The music is so painfully slow and dreary, just hitting the same few notes over and over, and I'll probably have to drag the tank out of the frostbite blizzard only to watch them run straight back in.

I feel like people must charge through and only unlock Snowcloak and Keeper of the Lake via MSQ, without touching any of the side dungeons, then run just those two all the way to Lv60.
