Stacking The Black Cleaver top is broken.
 

Building boots, 4 The Black Cleavers and a Guardians Angel is the thing to build for Solo Top lanes. This is pretty broken, and i hope this is fixed soon.

Yah it is pretty strong... But thats y u gottah not let them get that farmed also. Besides, stacking thirsters give u tons of dmg too.

I like merc, ruin king, blk cleaver, last whisper or GA then a warmog. N e champ can hit enemy armor to around 50 armors from 200. Thats just the items too.

Sounds like troll build and sub par as well...

-Attack damage is the only important offensive stat for many of these champions.
-Cooldown reduction gets better as you build more. That is why previous sources of cooldown reduction were unique, and the stat has a hard cap in the first place.
-You can never have too much health.
-Armor penetration has become a lot better.

The build is trolly, but it is not weak or stupid as previous stacking builds have been. Black Cleaver stacking is a potential problem, and it may very well be an optimal build for some ad ratio champions.

build health... get some armor to make it so you dont go negative but then it is all about the health... try penetrating my health with your armor pen
