Yes still full frost spec. Level 29 now. Cleared BFD until 27 now working on RFK until 32-33. Maxed out shatter talent which is really nice. So far have not had any issues. When mobs are 1 level below mine i can gather a couple packs and aoe them down with arc explosion which does make clearing a bit faster. Wish i had more time to play, certainly interested to see if this can be done in end dungeons. All good thus far though!
