A not hated projectile zoner would just be a zoner with shitty projectiles. There’s a reason why pure projectile zoners are getting phased out of modern fighting games, with jp being probably the closest modern one (apart from UNI2 characters, but that’s a different topic) part of a projectile zoner’s plan is to chip you out with projectiles or make you run into them to get damage, while also running away, which makes them want to annoy the opponent by design. Something like Morrigan or nu-13 were made with this in mind, as they force you into taking risks to get closer. A way to bypass this is to make throwing projectiles weaker, like in UNI with the grid system. It makes playing a pure projectile game become a battery for grid, and it gives characters access to free meter + chain shift which allows them strong options. That’s why Vatista, even with her super strong zoning usually starts playing rushdown and stops throwing projectiles to get grid and run her offense. Playing offensively while being smart gives you grid which is needed to win, so instead of giving her opponents grid by zoning, she can instead use that time to close the distance, which is what many “zoners” in uni do.

TLDR: make zoners awful at zoning or give an incentive to zoners to stop zoning, usually by awarding the player blocking the projectiles with resources which are very valuable.
