Jacqui has been nerfed a couple times, at least as much as Cetrion has. That's not to say that she's perfectly balanced, but she's definitely not going untouched.
I don't think there's a single top tier in the game that's gone untouched so far. It's just a slower and more measured process than the old games where someone would get instantly hammered to low tier.
Facts. And I am glad they haven't done that with MK11, for sure. The gap between bottom and top tier is certainly still there, but it's comparatively the smallest it's ever been in an NRS game, previously unviable characters or not. There has not been a Mileena VS Sheeva or Zod VS Lex Luthor level bad MU in a really really long time, and I applaud that.
What bothers me is the feeling that a LOT more effort went into making damn sure that Jacqui was great from the beginning and has stayed great ever since, having three of the best variations and arguably the best overall character design in the entire game. Meanwhile, you have other characters who look like their variations were thrown together at random, who LOOK like they were designed for a version of the game that was never meant to be hamstrung by variations to begin with, which is a huge part of why I'm still so against it. Open season for custom builds means a more difficult learning curve, which turns off casuals, who will always have the majority over competitive players in NRS games, so we lose out and end up with builds like Pitch Black, True Kahn, V3 Kollector before the patch, V1 Spawn, that Fujin variation that looks like it was meant to have the hurricane hands but doesn't because who knows why...characters were saddlebagged with unviable design flaws, while Jacqui, who was already on top BEFORE Upgraded was added to the game, got a brand new tournament build which put her so far over the edge that it had to be dialed back.
It goes back to my argument yesterday about developer's bias; you can't fully reinforce one or two characters while ignoring all the apparent problems at hand and not expect it to reflect badly on you. This last patch DID go a really long way in addressing a lot of those issues, and made several characters and variations viable that were previously not worth the time of day, and that should absolutely be commended. But it doesn't explain the special treatment that Jacqui specifically has had since opening day, that's brought about this argument to begin with. Who would want to compete in a game where they feel like the developers are more concerned with who THEY want to be good? Because to end up in a situation like this means someone or someone's made the conscious decision to put her on the top of the pile and keep her there, in spite of the fact that people have been clamoring for MONTHS now about how tired they are of fighting a character who has so many legs up on everyone else.
