To be fair the amount of people that use her well you can count on one hand. The rest just mash their brains into oblivion while tossing out random BURSTs.

Huh, if they even know the input for BURST. I love how unsafe Alpha is after something like her 6K string. Mmm the Choryo's are real when I see that XD

Kinda like FoN said, it can be hard to learn the MU when so feel people actually use her legitimately. But even if you are knowledgeable on the MU, that doesn't mean you have to like it. It's not my least favorite for sure, but I acknowledge that my character has unusual tools that make it less annoying than it is for others. If I were a Marie main, the Alpha MU would annoy the piss out of me.
