Possible archer hero spoiled?

I'd prefer something along the lines of still an archer, but weaker...

HOWEVER, gets stronger with a party, providing buffs, AND something like a special skill where you can borrow self buffs from other classes. Like, if you are near a NL that uses Shadow partner, you get the buff too, or transformation, but with a bow, etc.

Tweak it out a bit, and you get an interesting class.

Blue Mage class. Use enemy and ally skills as your own!
