Checking facts, I'd agree but in general I always found the Shaman as an offensive attacker, while the Druid would be a bit more... Passive isn't the word. The Shaman would focus on rage but the Druid would be calculating... If that makes sense? Again, I'm working off WC3 biases :P Spec wise, Feral (I think more bear/Guardian) would be the raging Druid and Resto shaman the calmest Shaman.. But remember, water can be calm like in a pool or as raging as a tidal wave, how destructive can a tree be? :P
Kerath, anytime. RPing a Draenei that eventually became a Shaman for years brings a little insight
