So if this multiple slot equipment is for limiting the capabilities of hibrids, why don't just change the requirements from PS,PD,PT to wpf? Let's say you need 140 wpf in 2h for flamberge, this would make archer-flamberge hybrids impossible, or from the point of an archer you need 2 stacks of arrows for a battle to be really useful, so if a bow takes 2 slots then taking 2 stacks of arrows means you have no backup weapon and possibly a kick because of running away.
