Okay thanks. I also have a few questions about the skidding stuff.
As you're skidding, JUST as you start dashing again, use the C-stick to fsmash in the opposite direction you're now facing, the direction you were originally dashing. If you time it JUST right, you'll slide across the ground in the direction you were going to dash very slightly, and f-smash at the same time, kind of like a retreating F-smash. Unfortunately, the game won't allow you to f-smash forward, but the retreating one has mindgames of its own. You can actually do this with dsmash, upsmash, all tilts(although to do a forward tilt you need to press forward twice during this, or set your C-stick to attack)and even your jab. The F-smash is probably the most useful use of this though.
How far backwards do you really move?
Is it really useful?
Is it a LOT different that this?
If you WANT to do a F-smash in the same direction you skid, you can stop the skid by doing something similiar to a pivot smash. Basically, as soon as you start skidding, you just have to press <>< at the speed required to do a dash dance, and then F-smash in any direction, as this will cancel out the skid into a dash dance instantly, and the dash dance will be cancelled into the F-smash. This is good for dealing with any issues which pop up, like an enemy who approached sooner and faster than expected, or a projectile.
How far does this go compared to the backwards one?
And do you HAVE to use the C-stick smash?
