3.25 is a hard swing speed to work with. you either need to maintain 150 stamina with 35 ssi on suit (easier now with morphious eppaulettes), or maintain 180 stam with 20ssi on suit.
the low stamina leech i dont see as an issue because plate / human give little stamina loss. it would be better if it was a bladed staff, but ive sold swords like this for around 40m
