I wouldn't worry about players putting everything into Wisdom just because of this; you still need very high Dexterity to even take most archery feats like Rapid Shot, so Dex is still important. If you want to deal more damage with composite bows, you need some Strength. Constitution is always necessary since everybody needs HP. Intelligence shouldn't be dumped because otherwise you won't have enough skill points. Really, it's still a very MAD class, but now Wild Empathy actually becomes useful.
And as for fighter, I'm not touching that train wreck! Fighter doesn't have any class features, nor even much fluff for creating new ones. I really don't see how I can fix that class without basically building a new base class completely from scratch.
