I don't really see any reason the scallywag shouldn't be full BAB. It only has one good save, and uses d8s... No class ability is powerful enough warrenting it being brought down, and if you want it to be able to parry often, I would suggest raising its BAB. Any particular reason you didn't make it full?
Anyone else want to chime in?
Lot of features?
Raising BAB now. I've thought about it several times.
