That's certainly one thing I do like about mages, but I'm also worried I wouldn't effectively be able to do the blizzard clearing, plus it didn't seem like the speed was too far ahead. I did aoe like 5 elites with my 4 mage/priest but I also struggled with bosses ultimately. Did you have a chance to do SM? Dungeons like that and on is where I'm worried my 4 locks or 4 mages may not be able to carry themselves with the priest and a tank would be needed.
