how is the black cleaver not currently viable? the thing about this change is you weaken the effective value of the item for champions that mostly don't use autoattacks to deal damage, and while it's not too big of a deal to work autoattacks into your rotation, it decreases the overall utility of the cleaver dramatically. now garen can't spin to win and reduce their whole teams armor, no fun vi can't just smash and dash, she has to waste valuable time aut0attacking her target while the enemy team prevents her from smashing on him. etc etc etc, the point is that black cleaver is extremely costly to reflect the fact that it's great to reduce their whole team's armor with a big aoe move.

yes, you would grant instantaneous armor % reduction but that ONLY helps champions that would be focusing a single target. in that case, said champion should be buying a last whisper anywhoo, the people that assassins and anti-carries dive DON'T have chunky amounts of armor, theyre building damage and attack speed, and removing the FLAT armor pen not only doesn't synchronize with the item it builds from, but reduced their output in general. and does jarvan iv REALLY need more armor reduction?

idk, it is nice that it grants more health though. I doubt theyd do that though because RITO goes OUT of their way to prevent bruisers from getting tooo tanky

I guess what im trying to say is that I'd be sad that its utility got nerfed, but would welcome more stats and a slightly lower potency, with the two seconds that you wouldn't have armor reduction. however I suppose champs building this should be able to secure a kill in about 4s anyhow lol
