Tengu being better in DOAD stems from the fact that his launchers were MUCH higher and he had more of them. You could do 1PP into 3P and juggle with 8PP T, for an example, whereas in DOA4 you'd have to settle for 8PPP.
Having same tools =/= everyone playing alike. You're basically saying if everyone had an unblockable they would all be the same move at the same height with the same input.
So? There are plenty of very popular fighting games that have clone characters, like Smash Bros. or Street Fighter.
And no one knows anything of Rio's martial arts capabilities. She could be the most talented of the entire cast for all we know.
A: No unblockables. Period. Though if he comes back in DOA5 I'd love for him to at least have the fire ball and make it unblockable. I mean, how the hell do you block fire?
B: Genra was only popular for those that only spammed his projectiles if they lost the round before. No one at all used him...

Her Power Blow is the same as anyone else's, having to be charged up, but it's used from her Double Jump stance! The string she used sent her into the stance and she charged it from there.
