all that does is balance it out to were it doenst matter what shiel you have which i dont like. A scutum should block more and absorb more, i kite shield should be close to that. Round shields should increase evasion so you dodge more and attack power so you hit harder. Id like to see things like spiked shields for this purpose. Having a system like this could make having 2 glads in one party more worthwhile.
also smaller shields should increase critical hit rate.
