Mournful needs to go back to Jade

Dragon Naginata needs to go to Hotaru.

Sonyas drone is stupid

I main erron black and scorpion so can only really comment on those two so if the next game only has two variations then these are tw I want for Scorp and black;

Marksman
Outlaw

Ninjutsu
Hellfire

Although I hope the next game ditches variations all together and throws in some more characters a roster of around 34 without DLC would be better

Let's just say they'll tone it back to two variations next game -

Cassie - Combine Brawler and Hollywood, or just lose Spec Ops altogether.

Takeda - Incorporate the pulse blades into his standard move set (or y'know, just give them back to the cyborgs), leaving Shirai Ryu and Lasher as variations.

Quan Chi - Sorcerer can be ditched completely tbh.

Reptile - Invisibility is adjusted as a universal special, leaving Noxious and Nimble.

Sub-Zero - Lose Unbreakable.

Scorpion - Move Raise Hell Fire back to his universal specials, ditching Hellfire variation or keep one of his demonic minions as a universal, ditching Inferno.

Kitana - Goodbye Mournful. Jade misses you deeply.

D'Vorah - Keep Krawler as a universal and ditch Brood Mother.

Kung Jin - This is a tough one. I'd say move one of his Bojutsu unique specials to Ancestral, keeping that and Shaolin.

Raiden - Move Teleport back to his universal, keeping Master of Storms and Thunder God.

Ferra/Torr - Lose Lackey.

Ermac - Another tough one. I would keep Master of Souls and Spectral for variety. Also, gimme back my universal Force Push.

Tanya - Agree with an above user. Give Naginata back to Hotaru.

Kotal Kahn - Lose Blood God.

Erron Black - Lose Gunslinger, but keep the hat for Marksman.

Liu Kang - Dualist can probably be trashed, or reworked for another character's variation.

Goro - Give poor Kintaro his Tigrar Fury back. Kano - Incorporate more knife based attacks into his standard moveset, keeping Cybernetic and Commando. Kenshi - Personally, I could do without Kenjutsu.
