I've been looking at Druid builds here, and I think I'd like to try a wolf-form Druid.

Should 5 feats be locked into Natural Fighting x3, Shield Mastery x2, to max out the double strike? If so, what should the last couple be?

Should I be human for the extra feat/skill point, half-elf for the sneak attack from a Rogue dilettante, half-orc for Strength, Dwarf for Constitution? (Is there much room for the looting dragonmark if human or half-orc?)

Advice much appreciated!
