stacking black cleaver in team should be punisheable

Black cleaver is a shred, and items like that should not be stackable by that it means it should be inefficient to get black cleaver on a top/jungle/adc

In league it's a bad idea to buy every item giving an aura or a shred more than once, like or old , or active or old WOTA once riot made the aura unique

however black cleaver is itself too strong, the stats it gives makes the item 100% requiered on almost every single AD and thus, if your darius has already black cleaver you don't act like "my toplane has already black cleaver i shouldn't buy one too" you just buy it because of 20% cdr+400 hp+40 ad this makes the item 100% gold efficient without its 2 passives that gives movement speed and armor penetration shred

and this is a problem since the 2013 version of black cleaver

abyssal scepter on the other hand is 96% gold efficient without its aura, which means if you have 2 auras the item is going to be less efficient and less powerful, which is also not true for black cleaver as the armor shred will stack faster if multiple people with black cleaver are going to hit

the more you know the better you are
