''Malzahar is uninteractive and his R is an instawin''
Except he has ridiculous mana costs, no mobility, no cc and bad range for a midlaner. Also he is forced to build the RoA/Liandri/Rylai rute because otherwise he explodes in the first TF he enters.
He is also one of the riskier midlaners in the game atm with the lack of vision, being an innate pusher with no mobility and no CC.
And his E alone has more interaction that some other champions' entire kits.
On top of all that, the 
buffs.
Just how salty are Zed mains?
