QI = Room restrictions, if new players play against more pro ones it will put the new players off playing the game, making it unfair.
QI really means nothing other than bragging rights, but some people would like to keep those bragging rights, some people(like myself) don't want to lose our QI in the next game and be forced to play the old game, if all players think like this, then it renders Next useless.
Obviously, not everyone will think like this ^^ but it's still something to watch out for.
