25% shred is just too much in combination with the armor penetration changes. They either have to mess around with the way penetration is done again, nerf cleaver or go through all the ad casters it breaks and tone down their numbers/ratios accordingly.
The amount of gold value of the armor they're piercing is too high.
At least that's what I think or how I feel at the moment. Seeing Black Cleaver Last Whisper in Kha'Zix' inventory makes me pee a little.
would it be impossible to imagine that they're absurd due to players coming out of the woodwork when people are dead-set on adhering to "squishy AP guy goes mid" style that they currently - and in fact always have, in the odd time you could do it without people dodging - counter?
I mean, the only real difference from S2 besides Cleaver/Penetration is that people don't think you're trolling when you pick Talon mid, after all.
