That would only solve the issue for manaless casters. Given all the stats are non-unique, you can still stack them. In fact, it's still encourageable to stack them because of the mana and mana scaling. Each item grants 400 mana, and so each item grants 0.8% armor reduction per stack. With Manamune and 4 Black Cleavers you have 3000 mana, which is +6% armor reduction per stack.

Actually, that's shit. That's shit even as a stand alone item. Even Urgot doesn't particularly love this and he seems like the intended user.
