Take restoration/balance (my druid now is lvl 38) - you do need some damage output, and weapon alone will not be adequate. I only use the stealth ability of the cat form, and the waterform - and the travel form, of course (at level 30, +40% speed!)
Don't underestimate the 'omen of clarity' spell. Weapon use will trigger a mana free casting for 12 seconds (the slower the weapon, the more often it activates) - so once its activated, you can cast a costly damage or healing spell without mana loss.
