I know it probably would've still been added anyway, but adding it during the submissions and all of that was a bad call, since they knew the same creature was part of a rigged submission even if that submission didn't effect the outcome. The problem with sino's usage is that it gets slowly worse the farther you progress into the game, as the abilities start to came into play less, unlike the Otter or Noglin, where their abilities are universally good no matter how far into the game you are.
