i haven't had problems with tsubaki. are you sure you're reading it right?
nah, bang and litchi are dead even. if you'd like, i could list the guessing games that go on in those matchups and that may put things into perspective.
tao is a bad match because she can easily get into close range regardless of where hakumen is. this used to be the case (in ct) while hakumen was in the air only, since he had aa 6A- which if you ask me, evened the matchup out. now though, his aa is limited to 5A (good, but no ct 6A), j.C (which tao can easily get around so long as she isn't sitting right at max range), hotaru (costs meter), and j.D (lol, really?).
the flow of most of hakumen's matchups goes something like this; turtle for a bit, then when you gain 50% meter/a decent life lead, get into close range and finish them off. against tao, however, you are almost always spending the time you should be controlling space with on the defensive. this means faster meter gain (if you can IB), but also several chances to get hit and eat a taunt loop. that, and tao has actual okizeme now (sorta), so you're often put back into the same situation after you ground tech.
in summary: it is hard to create space against tao, let alone control it.
the one thing that almost makes me want to put the matchup at even is the fact that at close range, hakumen's offense is incredibly scary for her. at the same time, that situation doesn't arise nearly as often as you may think.
