I used Raidou in doad to some extent, not as much as genra but I was capable with him.
His moveset looks pretty much exactly the same, only difference is he has this EWGF look alike. Raidous problem in doad was that his moves were extremely unsafe on block, like -13 or more. What sort of offset this was he had a few good guard breaks. 6 p+k was +5 or 6, 236 k was +3, and 214k was around the same I think.
His fireball was utter garbage, like every other projectile in doad aside from genras lightning. He could charge it to 2 variable speeds, a faster charge for a weaker fireball, or slower charge for stronger fireball, the problem here was that both were still really slow, and it was - on block. There was nothing stopping your opponent from just blocking it or evading it with a hold, just useless, you couldn't cancel it or anything.
Raidou did have some pretty powerful throws, but really wierd KOF like inputs. 6HCFT was the 30f OH, with a breakable T or 236236T followup. The 236236 followup was more powerful but had to be buffered to prevent being broken. Only problem here was the throw was 30f, which meant anyone competent wasn't going to be hit by it, he made audible sound and very obvious slow crouching animation before executing the move.
Raidous greatest strength in doad was his really good stun-launch, his 33k had these funny relaunch properties that allowed you to do stuff like this-
33k(launch)-33k-8p-33k-7k, from moderate stuns, you didn't have to go that deep.
If they just copy paste raidou from doad he wont be good, his lows are just too bad and his frames are god awful. They're gonna have to make sure he keeps his good guard breaks, make his 2p better,( it was 13f but like -3 on hit) give him better lows in general, the only decent one he has is bass's 1p. Just make him safer, no reason for a character to be -12 or more on almost everything.
I'll probably update this more when I get home and am able to go through raidou stuff on doad.
