Why copy? :(

JOKE
In all reality, these ideas are good, but I don’t think Purgatory needs to be updated. I think that they should rather focus on the current gamemodes, not the ones for banned players.
@McDonalds made a post about this right here and why an update is not likely/possible. Additionally, it isn’t really an actual gamemode many actually play.
@EvillRat’s post will also be of good help! 
No >:( again joke
As aforementioned, these ideas are pretty good, but I doubt there would ever be a future update.
