What is your Samurai's race, level, and current stats? If you're not too high level it may still be reasonable to max STR. DEX is extremely important for any combat character like a Samurai, so it's not like you've been wasting your points. Especially so with Bloodlust which grants extra attacks and Berserk, so the challenge isn't necessarily to max its damage but just to be accurate enough to hit with it consistently.
