DZ is way worst than any of those stage. At least on those stages you have changes to get out of situations. On DZ? No. You get hit with one move that can be the end for you. Can not compare that. That is no way a competitive level.
I agree to disagree with you. A good Leon or Hayabusa player that hits you on the home stage more or less murders you. I understand your concern about the TOD nature of that stage but I cant support the move to ban it.
