I have an earth/earth that just feels powerful. Earth control has always been my fav control powerset. The sounds are amazing. Earth Assault makes me feel like a brute.
ice/ice/ice is probably is my fav Dom. Once ice patch is down i just rain down the icicles and watch the mobs melt away.
I had a plant/thorny but rerolled as plant/fire and have enjoyed the results., Seeds+vines+carion creepers is fun to watch, then shooting some fire at the mobs is satisfying. i use him a lot in fire farms to pull mobs..
