@ Luigi talk
Just make Cyclone not able to kill ever and he'd be good to go. He can keep the combos with the damage and the incredible dash grab, but he should not get a Cyclone with a 45%-50% killing range on top of that.
Let him still kill with Dthrow UpB, Dthrow Bair, or Bthrow, because even then the first option has a specific range where it works, the second one requires bad DI on the opponent's part, and the third is his reward for braving through the onslaught for 155% worth of damage. Dthrow Cyclone not working only requires that the Luigi is stupid, so it'll never happen from an experienced Luigi.
Remove his "Imma Luigi, Number 1" combo, and there'd be little complaints.
