This is how I feel. Items stacking with themselves is lame, and discourages build diversity (especially in this case where an item has everything an AD caster could ever want).
If you want to max armor pen, you should be building a Ghostblade, a Cleaver, Last Whisper, and a Brutalizer (if you really want to), not 4 Cleavers.
I've never been a fan of same-item stacking anyways. In general, I'd rather have all champions building 6 different items in a game, and never stacking any item. Good for build diversity!
