Top 10:
1: Raiden obviously
2: Mileena
3: Johnny Cage
4: Takeda
5-10: D'vorah, Kano, Shinnok, Kung Jin, Jax, Sonya, Alien, Liu Kang, Kotal Kahn, Ferra/Torr, Leatherface. All of these characters are really good and deserve a mention in a top tier list for having at least 1 really good variation.
Bottom 10:
1: Raiden obviously
2: Unbreakable
3: Balanced
4: Fisticuffs
5: High-Tech
6: Cyber Scrub Zero
7-10: Hat Trick (?), Slasher (?), Brood Mother (?), Metallic (?). The last 4 characters are still decent enough (fuck you Wang
) so calling them bottom tier sounds a bit wrong to me.
