If you want aoe from a druid, consider trying a frostmourne with a druid prime charm. You get a sindragosa buffed up by %cold damage and cold mastery to help out with groups. (high damage to single targets as well) Admittedly, I havent tested this since I currently dont have a frostmourne. But now that it doesnt cause so much screen lag, this may be worth a try. Frostmourne also has high leech to help with survivability.
