i'd suggest grouping your druid with your bard and root rotting in halls of honor or any other hotzone. i've got a druid box at level 40 and i intend on taking her to cazic thule, siren's grotto and even hobgoblins. i figure if i just solo and have her in the group healing/dotting/nuking her levels will go up pretty quickly.
without your druid, i'd suggest heading to temple of droga (hotzone) and just finding a group. monste rmissions are good too but you need a minimum of three to do those. the BB one is the easiest. loot 31 and AFK.
