What does it do exactly? Reading the old threads gives the impression that 1 shield use rank ~= 1.5-2% damage increase for shield skills, with some rate of diminishing returns. Yet our new belts have double-triple the shield use rank and I'm hardly noticing a difference in the damage of shield skills, maybe 10-20% increase which can be directly attributed to the removal of the offense rating cap/diminishing return mechanic. anyone figure this out?
