everything that counters zed or is a good/very good, match against him
ends up getting reworked, nerfed, or removed.
let that sink in for a moment

Not Galio. He eats Zed for lunch and he doesn't get touched.
He still gets banned because there's almost nothing an adc can do against him, outside of a perfect team who knows what they're doing zed will shred every damage you have in 5 seconds flat using quickcast.
Zed is highly marketable, his plays look cool in tourney's, thus good for publicity.

I never really had a big issue with Zed players. Then again I main Kayle.
Jax is the #1 counter to Zed. even now Jax vs Zed is so one sided you could play jax for the first time and have a pretty close match with an experienced Zed.
Kayle Wrecks him and can simply stop herself from dying and E him away. while he cries because his ult was useless.
Wukong if played right can have a clone that zed ends up ulting (Plus his gap closing is unmatched)
Apparently Irelia is really good against him. Gap closers and such.
Malzahar.... well lets not talk about that slaughter house... Especially after 6.9
Diana does everything he does better (and looks pretty damn sexy while doing it)
A good annie can out do Zed really well.
Fizz is... well hes good against all assassins
Taric.... Enough said.
Lissandra im told works.
Vlad wrecks him (at least the old vlad does. I havent tried new vlad yet)
and the list goes on. dont complain about Zed hes not nearly as broken as people think.
