I play a shaman. I despise druids.
They cast Flight of the Eagles... this automaticly dispells 3 superior spells, Bih'Li (ATK BUFF), Acumen (STA REGEN), and Dead Men FLoating (Poison Save).
They tell people to click off Focus, the shaman big buff, in favor of their lesser crap that happens to include an extremely minor mana regen. This spell used to be in line with the cleric aego line, but somehow someone was convinced to move it over so that they could have both WoN and BoA. After clicking off your 1200 mana cast, they they have the gall to look over at the shaman and expect him to cast the shorter duration CHA buff they lost.
Druids wear leather, which is not a disadvantage, as in SoD, the leather has the same or nearly the same AC as chain, it's just lighter, usually cheaper, and usually has better stats. Yes, you can wear leather instead of chain, but that only makes the lacking all the more obvious, doesn't it?
Shaman shouls have superior health regens, as we begin to possess them a full spell level earlier. However, only druids get them in group versions prior to the mid 50s, and the the druid has a superior version to the shaman, for greater value, plus added secondary effects the shaman lacks.
The druid rapidly overtakes the mage in DS strength.
The Druid continues to recieve superior, longer lasting SoW (FoE), with included effects. The Shaman best SoW is at 39, with the duration of a level 39 spell.
Druids have decent DoTs, and excellent nukes.
Druids have snare, making soloing virtually foolproof safe.
Druid spells have inherent resist modifers that are already superior to the resist modifier debuffs cast by shaman.
They even have a pet, that while it may con lower or possess some mythical lesser stats, but is in practice every bit as capable as the ones fielded by a shaman.
Basically, druids have zero downsides in a game mechanics side, only the social stigma. Being a druid means never looking at another class and saying, "I wish I could do that", save possibly main tanking a raid. That would be stepping on a Monk's toes.
