Any possibility of going into Blighter? It's generally poor op-fu, but it might get you some of what you need. Wildshape Ranger on the opposite gestalt side may also help out, depending on what you want to do.
Well, the specific build is Arrow Demon HD 10/LA2/Fist of the Forest 3/Lolth-Touched Template 1//Druid 16. I have UA variants that trade Wild Shape and the Animal companion for Wis to AC, Favored Enemy, and the other benefits, since animal forms can't compete with the monster races everyone is playing in. Assume enemies will be fairly optimized themselves, though there are certain houserules in effect that prevent casters from running as rampant as they might normally. The general idea is Wis/Con to AC, outsider goodies, and full Druid casting, of course. I'll check out Blighter.
We have a way of reducing the LA...significantly.
