They're nerfing him as well

One of the other character classes we're looking at in 5.2 in Assassins. Some assassins have top tier burst potential that is loaded onto high reliability spells (think Akali or Fizz here) and don't have enough real weaknesses to compensate. Others may simply be too strong along a variety of dimensions; Zed being one of the best 1v1 champions in the game and an extremely efficient tower diver helps make him a super split pusher. However, him having such strong tower killing statistics (e.g. AS, bonus AD from W passive) on top of that makes for an overwhelming combination.
Riot admits that a secondary passive on a CertainlyT's champion is too much? What's next, Lee Sin nerfs? ;)
On a serious note, as much as I hate playing against Zed (not nearly enough as vs Fizz, tho) and never really played him myself, is it the best idea to nerf what's so good about him (1v1, pushing power)? Why not emphasize his weak points instead?
A simple yet effective change would be having Q deal reduced damage when going through creeps (like Sivir's Q). This way he wouldn't be so damn safe farming in lane, even under tower.
