there will be no ftp players when all the p2p players leave for good.this will happen due to poor support and fail events.
I remember seeing similar arguments, back in '09. I'm sure when the game finally does collapse you, and other doom-sayers, will gladly pat yourselves on the back for your "sound reasoning." But the truth is the game is still fun for a lot of people, and as long as that holds true the prediction will invariably fail. Many of the paying players from that era are gone now, replaced by others. It's a good bet that when the current crop of paying players leave they too will be replaced.
As for the F2P and P2P arguments, it's more a product of the class warfare present in our own society manifesting in our pastimes, same as it's always been.
