Yeah, I would aim also weapon supremacy with figther or if GM would allow go as figther but then enter 3.0 edition weaponmaster class and pick some nice exotic weapon (like mercurial greatsword or Spinning Sword and Shield combo and take martial maneuver/stance feats).
But aristocrat is my support char which is not too powerful but not too wimpy either. He could be kept manyways as monster girls pet because he has;
A) Hot looks
B) Daern's Instant Mansion (who girl does not love spa bath and luxury of a bedroom anywhere you want it, topped off by fact it's secure)
C) His Nolzur's Marvelous Pigments allows conjure permament items at-will, nothing powerful and he can create delicious dishes that way (his craft:painting replaces cooking skills as it depends on accuracy/quality of his two dimensional painting how good food tastes)
D) In tight spot he can fake knocked out/dead with his Combat Panache tactic.
Only what I wondered should I had taken Hindering Oppoturnist and then Stalwart Defender round up the fact in combat he is harmless but can be pain in ass to tolerate as he can perform AoO vs foes who hurt his buddies but he does not hit them but provides +2 to hit vs them or +2 dodge bonus to his allies.
