Swordsman Archive

I was wondering would carbinier 0/4/4/2 and swordsman be a good idea, for the reason of charge shot and the the counter att skill mod and the acc? I was going to be a doctor 0/4/4/0 so i can buff myself but theres not enough points so if i where to do carbine and swordsman together what would i use the other points on? To make me better? And also when your a swordsman your going to need doctor buffs bec youll kill yourself if you dont...so thats y i kinda want to keep doct?
