Hahaha, fair. I'm just really thinking about where to put in input that isn't basically along the lines of "no, seriously, get rid of most of those 3-7's, that's just not right". HLP is so often "who has the better option select sequences in stun and can make decent wake up reads?" and where there are relatively even spacing tools (which is usually the case, or at the least both have a reasonable way in). To distinguish properly between characters, I'd have to go to hypothetical rounds beyond certain moments.
For Helena, the only 4-6 I have solidly against her is Gen. I will vehemently argue against all of her alleged disadvantages that include Akira (no, if anything she's favored), Ayane (I feel really qualified to say no here), Rachel (if anything she's favored), Rig (she's in good shape here), and Sarah (actually a pretty good match up for her). I don't have a serious, considered 6-4, but might tip my hat at Alpha, Ein, Leon, and Eliot. There are other match ups where I have her favorably listed, but I don't want to blow that up into a 6-4. But her initial numbers are deceptively good; in theory, she has issues with Gen, Christie, Jann, and the others, but the only one where her options end up weaker is probably Gen.
Leifang doesn't have a bad match up to me. Not one. Not to Ayane, and definitely not to Sarah. Her favorables, however, are naer universal and relatively mild. Gen is the hardest match up for her, but probably his most even match up; I'd call it a 5-5. If fishing for favorables, I'd consider Eliot, Ein, Leon (seeing a pattern?), maybe Sarah (yes, really).
