I guess I could input that this matchup doesn't really seem as scary as it should, mainly because of Yosuke's mobility making a mockery of Yu's normals and shit. When Yu actually does get the sweep, they'll usually go for a few of the options below:
Empty jump 2A
JA or JB
Empty jump overheads
Roll overs and shit
and I think he can fuzzy, but I'm not sure.
Since Yosuke's 5D acts as a poor man's Yu 5D, we could learn a bit of his mixups and apply that to our own, if we settle for sweeps and stuff. Mostly what we SHOULD do is just run around and punish any normal that he commits to, thinking it is safe against us. Other than that, Sukukaja always seems like an option, keeping the pressure on Yu and making him use his DP for HIGH PUNISH. Another thing to note is that Yu needs to use resources to actually get any damage in, barring fatals. The most he can do is to wear us down with dem sweeps.... dem sweepy sweeps.... fuck those sweeps...
Also, be weary of his Raging Lions and dem Izanagi Cars, because that can catch you off guard. You can easily beat them with a DP, but you can also beat a raging lion with a 5A or 2B anti-air, and you can counter the Izanagi-mobile with dash spring, or you can block and dash 5A for a confirmed punish. Who doesn't love free damage, amirite? Am I right?
IN CONCLUSION: Yu has to space us out, which is alot harder than it should be because we can glide, moonsault, scary mixups, JD, and all that. All we have to do is just hang around or play extremely aggressively, minding his DP and his Bs that are the equivalent of Ragna's 5B. (Once again, BlazBlue comparison) All in all, we easily got this match in the bag until Yu gets a confirm in, and even then, his mixup is relatively easy to block... until he gets fuzzy... Fuzzy Lumpkins....
My overall assessment or whatever bullshit people do these days... I think... maybe: 5.5-4.5 to 6-4 Yosuke. Yu really needs to actively try to punish us or try to anti air us, and that is hard when all we do is glide and shit... and thats all I got to say... if anyone else has anything they need to add, go ahead and correct me if needed.
