This may be a necessary mechanic to understand to get out of the upcoming game's extreme disadvantage state
At this point it is well known that the duration of the hit in Super Smash Bros. Ultimate has been reduced compared to Super Smash Bros. 4s hit timer. To compensate for this, the knockback seems very "balloon-like" in the launched fighters will travel very quickly initially, but slow down after a certain point.
Despite this, many have been theoretically prepared that comes from the disadvantage of the state of Super Smash Bros. Ultimate will be very difficult. This is a result of deprecated recovery frameworks that are now associated with airdodging. This option is not as safe as it was in Super Smash Bros. Brawl and Super Smash Bros. 4.
Combined with the return-flying dodge mechanic from Super Smash Bros. Melee, this can be an important feature to understand in the upcoming game's overall meta. If you're like me, you probably did not even know it was anything before.
Of course, be aware that these clips come from a demo of the game. Everything is currently subject to change. Super Smash Bros. Ultimate will be released December 7, 2018.
