I was originally thinking of him being strength based, but dex based is a possibility, here's the reason:
He's part of a group of 5, leaders of a third party in the game, a sort of small country of mercenaries, that plays off of the conflict between two others. With these guys I didn't neccesarily go for optimized, i went for flavor, and am open to improvisation.
One is a warmage 8/argent savant 2/missile mage 5, with the mage armor feat (forget name) this allows him to wear heavy armor with no spell failure, he's a dromite, so you end up with a fully armor midget walking up and shooting giant barrages out of his hands, pew pew.
Then we've got our warlock 8/fighter 2/green star adept 5, gnome. He uses eldritch glaive, so we've got constructish gnome who makes glaive of dark magic.
Next is a ginger, er fire elf. He's a ranger 2 (elven variant w/two weapon fighting focus), monk (variant) 2/figher 2/ swashbuckler 3/champion of correlon 2/dervish 4 (may increase dervish). He has improved racial familiarity, giving him finessable elven baldes, and adds int, dex, and str to damage, as well as wis and dex to AC. Idea being finesse fighter, which is why I am uneasy with giving buggy some finesse.
5th guy I am still fleshing out.
So any suggestions? Also may go with custom made insect swords, that deal 2d8, based off of a 3.0 sword whose name escapes me. Exotic obviously
