The simple fix to SAM for it to fit the job's description is to primarily increase potency to things like their 3 combo finishers. Maybe even increase Midare from 720 to like 800 base potency. Or another idea would be to increase amount of kenki gained per weaponskill used resulting in more shintens used overall (Although this might widen the gap more from less skilled or lazy players who don't utilize hagakure and shinten compared to skilled players but that isn't a problem with me.)
