Shield Scaling - AP vs AD
I've wondered this for a long time now. For example - why does Riven's shield scale off bonus AD, meanwhile a champion like Lee Sin's scales off AP? Who the hell would build AP on Lee just to gain shield strength? I know Lee is still strong in the right hands, but this has never made sense to me. Watching Riven gain basically another free health bar versus Lee basically gaining enough to take a few minion hits is a little ridiculous.
