I don't have a whole lot of match-ups experience, but Scorpion and Geras give me a lot of trouble. I struggle against Kung Lao some, but I think that's just me being confused by his mobility too much and not being able to punish him (with D1) when he teleports. Sub-Zero also is kind of tricky because of his Low-Overhead mix-ups, but he has a hard time getting in. Other than that, I don't feel anybody else has a significant edge over Raiden.What are Raiden’s worst matchups at the moment? Feels like an uphill battle against most people since other characters command the screen much better than he does. Scorpion in both variations is a pain, Baraka is hard too.
Raiden has excellent mobility and the best corner carry in the game, plus an above average corner pressure. Once I get them in the corner, I usually do a ton of damage and most people struggle to get out.
