idk why giving 2 really good defensive items a ton of offensive stats was a good idea

These items were just fine before as situational defense items for everyone in the game, but now they're must buys for almost every AP or AD champ. Before the tradeoff for these two items was sacrificing damage for more durability and defense, but now you get the best of both worlds with just one buy. Not to mention it killed build diversity due to the fact that AP champs can't build GA without wasting gold and AD champs can't build Banshee's for the same reason.
