Seems like it should be automatic. You always have 8 crafting leves whether you want 'em or not. Shouldn't have to divide the other 8 between fighting/gathering. Or if the current ratio must be kept, let people pick which 2 get a full 8. Maybe some people would go 8 fighting, 8 gathering and say screw crafting. It should've accounted for all playstyles like that to begin with.
I don't think brief gathering leves are enough to drastically alter the economy, but if that's a concern make any new ones the kind where you're finding quest items rather than real mats.
