I'd do
1-10: WHM
11-27: WAR or RNG
28-59: NIN
60-75: NIN or RNG
NIN just for dual weilding Archer's and it seems like COR would be a good puller as the rolls barely take time to cast and last a good while, and A skill in evasion. Once you hit 60 you get Barrage which besides the accuracy traits would be the only real draw for a RNG subjob, Sharpshot sucks.
