For those that don't understand why people want to get rid of PPSC:
There is a fear that people 'game' the system. Basically, if you get second place a TON, but rarely get first place, you can rack up a ton of points. So those that go for the win and lose from time to time would hate the system, because it rewards someone who doesn't go for the win every game...
Of course, its highly frustrating when only 1/7th of the players gets anything from the game, and people would be recycling their 100 points constantly, otherwise, and the high pot games would be an extreme rarity. So, yes, I think they should stay, and I'm also not opposed to having other variants to keep things interesting.
