I don't get why some are hating on legit zoners? I'm not a zoner at all but I have used a few characters in that playstyle: Mileena, Kenshi mainly but I'm a rushdown player.
Zoning isn't spamming, the scrubs we see online using 2 or 3 projectiles all match are nothing close to zoners. Zoning is space control meaning using your moves to control your opponent and these characters usually don't have good close up tools which forces them to be creative. It can be done with normals that that push opponent midscreen/full screen or combos cut off that send the opponent away, yes projectiles are a huge tool used in zoning but they are based off reads. All of the projectiles have workarounds which allow rushdown characters to avoid them and get in.
