The most fun I have had playing lately was leveling 5-druid teams.

Questing is easier on a druid when they dont have to leave travel form for ground collection quests, can stealth past mobs, can queue for random dungeons even if all are dps, and probably other reasons I cant think of now.

I know if I have a 10 druid team I might not be happy once all I do is run dungeons. But I am tempted.
