Actually, RoA was meant to be an early game item, so they added the 20 minute loading time to prevent people from just buying it as a last item. AND RoA has to be a decent defensive item, even if the player is not doing well (read: not leveling).

Second, we don't need a cheap item that ridiculously increases your resistances, gives you health and a spell shield, AND increases your damage, for some champs (read: singed, ryze), while being totally useless to others (read: Zed).

Sorry for being so rude.
