Why we've decided to ban hero
As of August 14th Hero is banned at competitive events run by SASC.
After deliberation and plenty of discussion we have concluded that Hero’s design as a character is fundamentally dependant on randomness to the point that it is not reasonable in a competitive environment.
RNG permeates every element of Hero's design, from spell selection to random critical hits and hocus pocus effects. While randomness has to varying degrees always been present in competitive games and other Smash games, Hero is so dependent on randomness that it cannot be 'played around' or accounted for in competitive play. The argument is similar to the reason why items are banned in competitive play.
Additionally, even other random effects in the game, such as G&W's Hammer or Peach's turnips, still require the player to connect with the move. Although it is not a central issue, many of Hero's random tools, such as magic burst edgeguards, unblockable kamikazees or psych up critical shield breaks are frequently unavoidable and decide whole stocks. Random kill power and mobility buffs as well as free Zoom recoveries have no counterplay and can significantly effect the outcome of a match.
We want to emphasise that this ban is not because hero is too strong, but because he is anti-competitive. We believe that tournaments are meant to provide an opportunity for players to demonstrate their skill and that, as a general rule, the player who plays more skilfully should emerge victorious. Hero's design has a very strong potential to de-emphasise player skill which isn’t fair for those who work hard to improve their abilities for competition.
