are druids useful endgame on here as healers/buffers? or are they more of utility/"noraidspotsforyou"

Ogre is 15% and SK is 40% -- overall penalty of 60%

Theres a crapload of druids, but if you dont wanna play shammy/cleric, its a good option as well.

You might also consider a bard ....

Bard isn't a bad choice either... I will consider Bard or Ranger I think ;) Bards probably have a lot more groupability and soloability.
