Min/Max Boards

Hey. We're starting a new campaign from lvl 1, supposed to go long term. I can't imagine we'll go beyond lvl 12 or so. Anyways, I was pondering going moon druid. While they have a high HP pool for much of the game their offensive capabilities while shapechanged appear to very quickly trail off, not to mention the generally awful AC of beasts. So my question is: How can I get the most out of a moon druid? Are there any easy ways/feats/abilities/tactics/multiclass dips that can be taken to make beasts not suck so hard in a pure combat situation beyond like lvl 6-7? I realize versatility is a big thing with druids, and that's fine. But are there any good ways to try and min/max the offensive output a bit more while shapechanged?
