Fixing Zed's New Ultimate Passive

This hasn't happened to me yet, but I'm feeling tremendous fear locking in Jhin without Zed banned. The idea of a Zed picking up a bonus 120 AD from my dead body is terrifying, and effectively game-ending. A nerf where Zed picks up the AD pre-passive would put things back in line.

I'm also confused why Zed doesn't pick up 2/4/6% of a Mage's AP as an option, or 1/3/5% of a tank's bonus HP. These seem like ways to make him more sane.
