personally i found that cage and sonya didnt feel that bad(despite them both having auto correct nonsense, though i think sonyas projectile recovery makes it risky to tele, however u can block the dive kick sometimes if u tele, also its hard too really damage cage if hes played correctly), cyber sub was weird but u can superman him a lot and zone him out
i found that kabal, kenshi, reptile, kung lao, sektor and kano were my toughest matchups because they nullify his space control and make him change is game... some of those are 5 5's probably but kabal and kung lao feel really limited, sonya can be bad but i find myself punishing the shit out of her.... it really depends on how good raiden actually is, i think his offense is too limited and that he actually has quite a few iffy matchups... though he clearly changes the opponents game.... i think that its a common misconception that he blows up pokes with his teleport
