The true damage only comes when you've auto-attacked 5 times (and for 6 seconds only, with a 20 second cooldown), and the armor shred is post-6, and for that you (again) need 5 passive stacks. Few melee champions, even juggernauts, get to enjoy using 5 basic attacks in a fight. For a 15 armor reduction, having to go through all that trouble, well, it only rewards him for having kinda won the fight in the first place. Since the effect is so temporary, I don't think it's that broke, now is it?
