Going back to the
MU, I'm just gonna say that it's pretty awful. No way is this in our advantage, or even considered an even MU. Both characters have a common goal, and it's to maintain stage control. I admit, once Zelda gets Rosalina off stage, we have plenty of options to edgeguard her. This includes the Dtilt trap near the ledge, as well as easy Lightning Kicks (Rosalina is fat :^) ) and Uair kills. And I noticed with Nairo's match against Dabuz that dash attack was used a lot to get Luma out of the way, making it a lot more manageable.
HOWEVER, this is where all the good stuff ends. Both characters want to maintain stage control, but Rosalina just does it SO much better. She has amazing aerial game, and her ground game is heavily enhanced due to Luma. Nairo in that match had a whole lot of trouble getting back on stage after grabbing on the ledge, just because Luma keeps you COMPLETELY in check. No reason whatsoever for Rosalina to commit to an edgeguard when Luma already does it so well. Most of the time, she'll be controlling the stage, and you playing catch-up. Once you're off stage, it's a HUGE struggle to turn the tides. Even without Luma, Rosalina is basically a better Zelda, so I still don't consider it to be an even MU. It's like when Luma's gone, it's so easy to tell yourself that you got this, and you end up playing worse because you have the mentality to kill Solosina ASAP, and it gets to you. When the MU is basically kill Luma just so you have 13 seconds to CATCH UP, there's NO way it's favourable. It's not our worst, that's for sure, but it's pretty bad.
Oh, and not to mention those easy premature kills as well. Crazy.
