If they added shields that have an op bash knock-back feature that you could use alongside standard blocking that would really change up combat mechanics. If someone was all up in your face you could just be like:"Ha! Noooppee!" In terms of alliance crests on shields that would be irrefutably epic!That actually would be pretty awesome. Or if you could have shield skins, perhaps. I think it would be crazy to see alliance crests on shields.
