Remy is good, but he can only be good by different means, aka the endless barrage of projectiles, and knowing when to time them. His standing MP is kind of like a shitty anti.
I use this stuff, since I repaired my agetec stick and I can play fighters again.
charge b f b, then I do this over and over. I swap it to a mix of different speeded sonic boom's.
So we got bfb WP, bfb WK, bfb MP, then you can toss in others awesome mix's. bfb KK bfb MP bfb KK, bfb PP. Etc. This is great because unless someone is sick at parrying, it will fuck em up.
I agree with wes also, his normals suck, he has no cross up ability like Ken. He just fucking sucks at stuff that others have ontop of already great shit.
BUT
If you stay on top of those projectile mix ups, you can sit pretty. Its funny because I finally got the flow to this garbage down last night, its hilarious what you can do with it, if you get that flowing properly you can keep doing bfb PP bfb KK and link all of them together.
The timing is strict, but you can half ass it by letting the first projectile ride and when it hits or is about to hit, toss out another and flow them constantly. The trouble it seems is that when someone jumps in you gotta watch out.
My friend Miguel uses this trick with remy where he throws a projectile, if you parry it, hes already rushed in for a throw.
