Riot - How are you going to help Riven, Zed, Kha'zix, Kallista, Kindred

The first 3 are sitting at something ridiculous like ~ 43% win rate right now. Most of them were top tier champions before the patch hit.

What do they all have in common? Their kit doesn't work well with crit and they relied on high ad + old last whisper to do damage.

Riot seems to have completely forgotten that champions other than adcs used to use old last whisper. Riot needs to help champions who just want to build a ton of ad + armor pen. They can currently pickup a grand total of 20 armor pen from items.

AD assassins need an equivalent item to Lord Dominik's Regard to shred squishies. If an enemy champion has lower total health than you, gain 50 armor pen vs that champion. As long as an item like this doesn't exist, champions like Kha'zix will continue to be trash no matter what Riot does this preseason.
