Do you really get the benefits from the Two Weapon Fighting and Ambidexterity feats when shapechanged?

IMHO, if this is true, adding one level of Ranger is just as good for a Druid as it is for a Rogue.

I don't believe you do - you use "natural" weapons when shape-changed and I don't think combat feats apply to them (maybe there's a mod somewhere that would change this, but the game out of the box doesn't AFAIK).

The 2 classes I have seen that can boost the wild shapes are Monk and Barbarian, have never seen where Rangers can use dual wield if shape-changed tho.

Cool, thanks. It was Monk I was thinking about that gets his boni while animal shaped, not Ranger
