It's not just the passive. The passive itself isn't too bad, to be honest, even if you apply multiple stacks per hit. The issue is that, with four of them, you have the health of a, +200 attack damage, maxed out cooldown reduction, and 60 armor penetration.

Given that flat and percent penetration now play nicely with each other, and a passive that procs on all physical damage instead of just basic attacks, that makes for an unbelievably good item for fighters that only gets better when stacked. An absurdly good item for fighters.
