Her difficulty to unlock should be a reason to consider.It really sets people back having to find a console and profile that has her ready to go. Look at SBO, there was an issue with the profile not having gen-fu i believe it was. A much much easier to unlock character. It delayed the tournament 10 minutes because in a tournament setting it is never easy to move things around. For the TO's own sanity I wouldn't mind seeing her banned. However if TO's don't mind having someone spend the hundreds of hours it will take to unlock her on a handful of consoles then that is up to them. I have no issue playing against her as a character.
As I stated in the official rules discussion thread, the ability to have a save or not is up to the TO to properly announce if she will be playable or not.
By saying you're "banning" a character, you're saying that the character is not allowed EVEN IF THE CHARACTER IS SELECTABLE.
Are you going to ban Pai too because she takes 100 titles to unlock? "Oh, but it's
only 2 hours to go through story mode completing the bonus missions." Yes, that is true, but that doesn't change the criteria you are labeling for the REASON you want to ban Alpha-152.
A character should be banned if their move list literally breaks the game and cannot be avoided. Not because it takes a while to unlock them.
Again, players who main her will need to ask the TOs for the tournaments they are looking to attend to know if Alpha-152 would be playable. It is up to the TO's discretion on if they want to unlock her or not, as well as what other unlockable characters will be unlocked.
