But the rise in % essentially makes your stock gone anyways. Another potential gimp off the stage and you'd be good as dead anyways.
I beg to differ. The Floor is 15% I believe, and you might take another few hits (SDI and Shine can help you avoid that however), but that's still better than outright losing a stock, not to mention you can do the exact same to other characters.
I wouldn't recommend taking Kirby, MK, D3, Diddy, Pit, or a few others here, but bringing characters like ZSS, any of the Starfox characters, Lucario, PT, Mario, or Oli, to name a few off the top of my head, is a great idea.
Honestly, very few people have messed with this stage, and I personally feel most people think it's way worse than it actually is for some characters (although for some it's pretty horrible, I admit, and for MK/Kirby/D3 it's pretty godlike.).
