I have also dropped whorealinaWow. You can combo Falco's b-air or f-air off his d-throw. N-air also can combo off from d-throw. Facing backwards with n-air will get all the hits to connect for some reason unlike using it forward. Also, you can get b-air, and f-air off from u-air. I managed to get u-air off from u-throw but it's a bit too difficult to execute anyway and it's probably avoidable by DI. Anyway, neat stuff. I guess.
I tried to use Rosalina for quite a while but dropped her because her style felt too slow for me. The only character I've yet to try is Dark Pit
She's not as OP as I thought
Now I play Sheik /tears
I might upload some videos of my Sheik one day
