I never feel like split damage weapons pack enough punch, so I'd say swap out the greatscythe and claymore for a Moonlight Greatsword and a Moonlight Butterfly Horn. Pure magic damage, and the MLGS is arguably better than the claymore overall.
@SirArchmage Thanks. Exactly what i was looking for. @Sneezer Split really doesn't bother me that much. I know I can switch those out but i get bored of using the same weapon most of the time. That is why I'll go from MLGS,to Enchanted Claymore an so on.
