I mean I use him, but only as a sub. Well, not even a sub. I just hate that the community is so small sometimes. That's why we have so few character specialists and loyalists. Less people playing = Less people to be interested in different characters.
I know a few people who used Raidou, but they already had other mains. Mine is still not in the game(Genra), so I'm stuck with Raidou and Momiji till then.(aka never)
I'm pretty sure almost any character on the roster can be "dangerous" if people actually put the time into them. Most Western players are lazy shits however.
The one's that aren't lazy are usually the one's that make it out to tourneys and kick ass. Kwiggle warned us that the split between competitive players & lower level players is becoming larger. One of the more frustrating aspects of the DOA community is that no one really discusses character developmental things and instead choose to whine about online gimmicks.
If you want to dig through the raidou thread there is some tech there, after this semester is over I hope to find some more. I struggle hard atm against characters who can stay in against raidou, need to find a consistent way to keep up pressure.
