I know what Eliot can do xD His linearity and somewhat slow speed as well as lack of good MUs overall drag him down, I mean I could at highest place him as a C but he would be the lowest in the below average class. And Kasumi is really high because she has speed, evasion, good throws, defensive holds and a expert hold CQC, and good enough tools to help her do well, her lack of safety and damage however drag her down from being in S tier
Her mix ups aren't all that tbh XD the scariest mix up she can do is throw out a mid punch when she does her 5K or 6K kick strings, her other mix ups are either predictable or too slow to be of use. Her damage is good but not great either, its average and you'll have to work hard on high level play to get even that
...Wait you meant Phase??? XD Yeah, the scariest her mix ups are when she starts to teleport since you have less than a few moments to react or else she can keep going or bait a reaction and throw you. But she's not all that great. If she had Kasumi's mix ups and more safety and a faster neutral she would be higher but as long as she's fighting a good defensive player or a turtle, there's not much she can do and she has a tough time opening up defensive players. If speed was much a factor to a tier list than Pai would be S tier since she's possibly the fastest in the game but her damage is poor and she has to work for it. Bass is also very powerful and has scary HC throw damage but his speed drags him down since the game favors speed. Gen fu has speed in close range and great power as well as defensive parries I believe and good pressure which is why he's so high but his nerfs made him less braindead. Leifang has decent Close range speed and sabaki, parries, defensive holds and expert holds for all hit levels which makes hee great too but her lack of speed from a distance to help her move in hinders that a bit. Christie is fast, has pressure and power and really good evasion but her meh hold and throw damage hinder her in that regard and i don't believe she has any scary lows either nor many good defensive options
