The substance of what you're saying isn't wrong, but we all just saw a top-level tournament player actively campaign for the nerfing of his universal tools, like his plus frames. He didn't say "oh, just give the low fireballs a wee bit more recovery", which wouldn't bother a single day-one Cage player here. Instead, he called for basically taking away everything about Johnny that makes him Johnny.
Furthermore, Johnny players - who have been using him before Outtake was even thought of - have had to fight these ridiculous matches against characters that we might actually go even with, except our main tools(high jailing forceballs and high pressure/combo starters) don't even function properly against these characters simply because NRS can't make a consistent hitbox to save their lives. We've been fighting against these characters using Shock Jock, and then later with Showstopper, whose tools didn't work any better, but he at least had a KB and unbreakable damage.
Suddenly, Outtake comes along and now we don't even have to worry about whiffing forceballs anymore because a previously-useless move was made obnoxious. So now, Johnny is finally consistent to some degree against most of the cast, but what do we hear? "Johnny needs to be nerfed", "Johnny is stupid", "Johnny beats everyone in the game".
It is both quizzical and comically annoying, because the moment that a good character with a lot of potential - that still has unfixed whiffing issues, a single slow, non-comboing mid and virtually no KBs - finally gets a bit of consistency and some tournament wins, suddenly he's the #1 character in the game when Cetrion, Cassie, Geras, Liu Kang and Jacqui still exist., and should get hit with the nerf bat because people don't want to walk and block a fireball.
I'll end with this: NRS should give JC's low fireball a few more recovery frames so that people don't feel like they're being zoned out. In exchange, we need ALL HITBOX INCONSISTENCIES FIXED so that Johnny can be himself against everyone in the game. I don't even care about his lack of mids or KBs, just let our forceballs and highs jail on crouch block consistently against everyone.
