Since ammo becomes very expensive, would it be better in the long run to level in crafting to produce the ammo yourself? Also, what crafting skills would i need to make arrows and bullets?
The most important aspect of this game is to have fun. Yeah, some job/subjob combinations are better stat-wise, but if you wanna be a Elvaan RNG/WHM by all means go for it. If its what you wanna do, make it work and have fun.
