I really don't think arguing with Nagash is a great idea. Its great you want to get more people to play, but instead of a challenger vs falldown match would it just be better to have a whole tournament wher efalldown is entered in? That would allow more people to enter and some to watch. But the chances of that happening are slim since the last time I tried that not eniough people showed. Since Nagash said something about updates this week maybe that will boost attendance and you can work from there. Just try not to argue too much with him.
