@Force_of_Nature That's just because no one is using her at that level yet. She's got Parries, Sabakis, offensive holds, tracking, plenty of guaranteed damage, a devastating wall throw and reasonable enough options in spacing to get her by. The only thing she truly lacks is player. She has everything she needs to win and is one of the most slept on characters in the entire game.
The same can be said for Helena and Christie, people seem to forget Helena is unsafe on nearly everything, 90% of what she needs to use to open you up are mid punches and unsafe lows that can be reacted to (offline) and a lot of Christie's stuff can also be stopped like 2Ping her out of JAK on reaction (as long as it's not double JAK).
I'm not saying that they aren't ridiculous but Lei is as well, she just needs a bit more work but a Lei with momentum is arguably just as scary if not scarier if the opponent knows what they're doing and are using all of her tools effeciently.
