I maintain that it's still one of the greatest OoS moves even without the invincibility.Whoa, did you guys know that Whirling Fortress no longer has Frame 1-5 invulnerability in this game? I was totally kept in the dark about this. With a frame 6 hitbox, it's still a good OoS move - faster than any other move Bowser can perform on the ground, especially with the fact that it's an up special. However, I'm still quite depressed to have found about Bowser no longer having one of, if not THE greatest OoS moves in Smash.
That speaks volumes for how amazing it was WITH it.
