What makes a druid good in a group as opposed to just average.

[shams]

Just wanted to get the community's opinion on what makes a druid a good and worthwhile addition to a group. I play a lvl 28 druid and have never had a problem finding a group, though I find that when I'm not the main healer, I dont really have much of an influence in the group. My DPS is mediocre-average I would say when I'm not in a healing role. I normally try to keep the MT damage shielded as much as possible as well as keeping everybody else buffed with whatever is needed.

Other than the stuff I listed, is there anything you guys find exceptional when you're grouped with a good druid? I'd like to take whatever info I can from you guys and apply it in game. My toon's name is Sooby in-game, so please feel free to let me know if you need something extra from em if we're ever grouped together in-game.

Thanks!
