Obviously

I'm the sort of player who deliberately avoids such rules abuse.
1) It's legal. You just had to be lawful neutral.
2) Alignment has nothing to do with game balance. It was simply an intrusion of rules on roleplaying.
Wildshape lasts hours/level, making the activation time nearly meaningless. Once you hit 5th-level, you might as well be wildshaped as long as possible, as long as you weren't involved in social interactions. (You can do so for 21 hours per day at 7th-level, and IIRC you couldn't dispel it either.) Once wildshaped, enjoy your Wisdom bonus to AC! (And whatever other monk benefits might apply.)
Druids weren't as good at buffing as clerics IME. They tended to be better at blasting though. But if you had a round to cast Barkskin then, why not?
(And on another note, a reasonably built cleric who reached 9th-level could nearly match a fighter in combat with a single spell. No need for a long buffing suite.)
