Raiden cant kickstart almost all cast even when they are crouched, he has some tlpt shenanigans here and there but thats all and a nice damage output on almost everyone.
Cage has the lowest damage output in the game, maybe even less than Sektor, can punish some stuff but does crap dmge, his standing Hk and Lk have very good range but since those are moves punishables on block + gjabs then those are almost worthless.
H Smoke has damage chances of 50% out of almost ALL situations (aahp, aarh, spear alone, pop up, relaunchers, can inf lp on corner from a spear, etc etc), and for Scorp he just lacks good dmg outsite of aa punishes, he can annoy a lot, fwd tlpt punishes blocked sweeps easily and other stuff. Comparing R vs H Somke its just about tools, Invis is DEADLY on its own but gjabs can shut down SOME of the invis tactics. R Smoke has the fastest spear in the game and can punish moves on block that H Smoke cant like NW SS etc. Both have air throws (R Smoke being here far superior), but R lacks the escape ways of H. Both have godlike normals.
