My main is Jiggly, but I like Luigi a lot in this game! He's really powerful, had awesome combos with his grab. I love how Jiggly plays but I wish rollout was like in smash 4... It was great to break Shields.
I also play Lucas, Lucario, Dark Samus, Samus, Falco and Zelda really good, and I used to play awesome with Olimar/Alph in 4 but now it's like I have some problems with his combos, I don't know.
I play mostly like I used to in for Glory, Omega stages, no items, no final smashes, 2 stocks.
I'm loving the game so far.
