Top 5: Raiden, Liu Kang, Shao Kahn, Johnny Cage, Cetrion/Noob
Bottom 5: I sincerely have not many ideas, but I don't think I'll be playing much of Baraka (haven't played much on Beta), Skarlet was good, but same of what I said earlier, Jade and Kabal were great, but I think I have already extinguished a lot of my hype of playing with them, and Jacqui looks better, but not hyped for her gameplay.
Just some honorable mentions: I played Scorpion, he was great, I expect to see more of Sub-Zero, I'm excited to see how time rewind works for Geras, really wanna make some kombos with Sonya, Cassie might be a good one, I had a good time with her (when I wasn't getting my ass kicked in the last chapter), Jax seems way better, and I do wanna play Kotal, even though he doesn't play the style I'm more comfortable with.
