My main problem with the codeset is vertical kill moves don't kill like they should.
e.g. Snake's up tilt, DDD'd Up tilt, Mario's Up smash, samus' down tilt.
This is unfair on characters who kill vertically (e.g. samus) but characters who kill horrizantally and Gimp actually get buffed from the added gravity making it harder to reach to the stage then there is the No ASL which helps edgeguarding/hogging too, a big issue IMO.
second problem is falco's shine.
it is dis-jointed, it reflects projectiles, it is fast, it goes far, it spaces, it has priority, it combo's into his one of his main kill moves (Back air, which is crazy considering you opponents cound be on the GROUND on the left side far away from falco and now they are just behind on the right in the AIR).
there is no reason falco (who is a beast) deserves it.
