Alot of what I’m about to say has already been covered, but:
Marrow needs to move up significantly. She’s Third Tier for sure. She can punish assists really well, and the wierd properties of her Bonerangs can trip people up a lot, and helps her fight Spiral (Marrow isn’t a Spiral counter, but she fairs well against Spiral thanks to her Bonerangs amongst other things).
M. Bison, Morrigan, and Sakura need to move up one tier. They all have abusable strats and tacs that allow them to at least beat everyone else in your Fourth Tier. Morrigan has a good rushdown, enhanced by her strange air dash. Sakura also has a good rushdown and one of the few good dash assists, plus when she turns Dark, she can really put the hurt on and gains that no-lag teleport. M. Bison has a lot of safe chipping patterns from what I hear, and some good comboes.
Ken and the other two shotos are too spaced apart. IMO, Ken should stay Second and Ryu and Akuma should move up one. At the very least, Ken should drop one. As Dasrik said, Ken isn’t that much better than the other shotos. I think he should stay Second Tier though, thanks to some good assist punishing abilities and the instant statup on Sho-Reppa-Ken, plus the good Anti-Air.
Felicia, Silver Samurai, Omega Red, the Hulk, Venom, and SonSon are all Second Tier. SonSon has some crazy cross-up options and some good comboes, including being able to combo her staff super at the end of her anti-air move for some good damage. Her anti-air is a good assist, too. Venom can hang with all the other Second Tier mainly because of his Venom Fang. The move has no punishable lag and good start-up, and can really be abused when you learn to use it right. The Hulk has a safe Gamma Charge and some simple but high-damage comboes, plus his dash-j.sk is crazy good. Silver Samurai is most definitely high Second Tier. He can’t be thrown while crouching. His Shurikens do good damage and good chip, as does his Triple Shuriken super. Ramaiken is really good at punishing assists, and he can combo from his Ice super into Ramaiken for great damage on the point character. His normals have great priority. Finally, in his ice form, he gains better-than-Sent defense. Omega Red is an unusual character. To be honest, I know little about playing him. But I do know he’s a good battery character, he gives StriDoom a good fight, and Omega Strike is relatively abusable. Felicia, on the other hand, is my pet character. She outright counters StriDoom, as long as she has an AA or Sent behind her. She’s a great battery. Ground chain -> Sand Splash is highly abusable against most characters. She can punish assists with Hyper Sand Splash, as long as her point opponent doesn’t have a really good dash (Mags, Cammy, the Wolvies, etc. are unsafe, as is Cable thanks to that damned pistol shot). Hyper Sand Splash has stupidly quick start-up. Felicia can even hit Mags off of a blocked c.sk with it. Her fp throw builds 3/4 of a meter. Her s.rk has abusable priority.
I also feel like Hayato should be Bottom Tier. He has no projectile/beam moves, meaning he has to play rushdown. But he has poor speed, a mediocre dash, and no air dash, double jump, triple jump, wall jump, or teleport. Basically, he’s a rushdown character with poor mobility and nothing to help him get in. I’ll grant that he has good comboes, but his odds of landing a hit are slim compared with similar character, and he has nothing to fall back on if he can’t land a hit.
No. Guile is higher than Charlie. Guile’s ability to throw air Flash Kicks gives him a ghetto double jump, and he can even take on Storm with that (see Zaza). Guile also has a good rushdown pattern with ground chain+cover assist -> fp Sonic Boom, cover assist hits, repeat. And Sonic Hurricane is better than Crossfire Blitz, plain and simple.
