I would mod
GGA 16 Bit Body and face into Kitana
With full quotes and trash talk... the popoff after winning... this would be epic.
First and foremost, remove the input bug and meter drain glitches.
I would give
Sub-Zero back his ground freeze reset... that shit was too gdlk and he needs it.
Jade would get hit confirm overhead staff from standing 12... and standing 3 would have more range.
Ermac EX teleport hits mid and has advantage like Scorpion's.
Baraka would recover faster from blade spark and you can 2-in-1 all specials except blade fury from f4. Sweep comes out faster.
Sindel can 2-in-1 scream from standing 4 again (remove infinite)... and cartwheel is -5 on block up from -7 so she is not full combo punished by 6-frame moves.
Smoke's OTG removed... also projectile parry will have more startup.
Noob's zoning will recover faster so he can actually zone outside of full screen... xray damage reduced slightly. EX teleport now ground bounces for a combo. Also full invincibility on up knee as a wakeup attack.
Kano knives returned to normal... ball given a fucking sound effect (lol)... additional ball motion added alongside UFDB (BF motion). Some normals recover faster (212) so he doesn't feel so damn clunky.
Cage f3 to be -2 instead of 0.
Kenshi spirit charge has more recovery and full combo punished up close. EX spirit charge builds less meter on block and has a few frames less advantage. Overhead sword active hitbox slightly shortened to make it easier to dodge on a read. (come at me bro)
Mileena... you can dash out of the second kick of EX Telekick if the first one is blocked with all characters.
Shang Tsung has one frame more recovery on close ground skull so characters with slower normals have a better chance of poking out of f4 pressure.
Sonya EX cartwheel more negative on block. Range on d4 very slightly reduced.
Cyber Sub-Zero's teleport works exactly the same as Cyrax's how it leaves behind a hitbox that forces a block animation on his opponent's attack if timed correctly. EX teleport and freeze both have much faster startup.
Kabal now has a height restriction on iAGB. Standing 2 has slightly less block advantage.
Cyrax... lol how do you fix a leaky boat?
Kung Lao EX teleport armor extension glitch removed.
I cannot comment on Skarlet, Rain, or Freddy as I have no real knowledge of the characters.
