@Jeff Kuta--
"I think we should encourage as much newb-friendlimess as possible."
To be fair...pretty much any scoring system that takes more than five words or four-function arithmetic to describe is not newbie-friendly, even if it's straightforward/intuitive for experienced players.
PPSC: "Number of supply centers."
WTA: "Winner; or, survivors draw equally."
SoS? "Winner; or, the square of your SCs over the sum of the squares of everyone's SCs. No, it's not your SCs squared over 34^2, it's something else. Yes, that means your score with a certain number of SCs depends on the distribution of everyone else's SCs. Yes, it's non-linear."
Carnage? "Survivors are ranked by SCs, losers by order of exit--in the thousands, so we can have residuals to break ties in tournaments, which you don't play in but we expect you to care about. Oh, and winner still takes all. Yes, that means the survivors determine whether you receive points for a defeat, sometimes a decade after you were defeated. I'm sure that never causes any problems, though."
So, while I think PPSC isn't a theoretically good system, I also don't think replacing it encourages newbie-friendliness, and adding Carnage wouldn't either.
