Simple fix for ZAC
Since his rework, getting almost double the amount of cc that he had before but retaining most of his damage, ZAC has been a top pick/ban even in pro play. A lot of this has been from the power of his early ganks where he E's in, but even if you dodge it, he Qs a minion and uses the extended auto range to bring you back.
A simple fix for this would be if ZACs Q only gave the second part if he landed the skillshot on a champion or a large/epic monster. That way ZAC has to land a skillshot in order to cc you, but he can still use it in the jungle, or auto a minion in lane if he lands the skillshot on you during a gank
