Balance Druids: Your job is to crowd control, buff, and mostly to do damage. Your a great big target in Moon-kin or caster form, so stay back behind the meat shields.
Heal if you have no better use habbohotel coins for your mana at the time.
Alternatively you can be employed to hunt enemy farmers (who hunt rams/wolves) - plenty of 1on1s and you keep them from using their special abilities.
Eye of the Storm: This battleground is a combination of War-song Gulch and Arathi Basin. There are four towers to capture, each tower owned gives a flow of points until one teams reaches 2,000 . A flag can be captured in the middle of the field and run to a owned tower for bonus points.
Druids do as well here as they do in WSG and AB. The same strategies apply, for the most part.
The trouble with EotS is that everyone on the field wants to run the flag. This is a losing strategy. Owning two (or more) of four towers and capturing the flag is a winning strategy.
This requires most of the team capturing/defending towers, and only 3 or 4 players contending for the flag
