So I know this isn't that big of a deal in the game, and there's plenty of other things that need to be addressed, but one thing that I think the game needs is more diversity with player icons.  I think that a good idea would be to have the icons of all the heroes incorporated into the icon selection, but locked until you summon the hero.  That way when people summon cool epics or legendries that they like a lot, they can choose to use that hero's face as their player icon.
