The Iron Coins is supposed to be part of that, which obviously isn't enough on it's own for many players right now. The assumption is also that there is inherent value to attacking, in that if you're attack and your attack + defense win rates are better than your competitors, you'll end up in a better place than others who started at the same points as you (regardless if they're standing still, participating less, or participating more). I definitely agree that the current matchmaking is probably not doing that, but considering the experimenting player is effectively standing still, and the rush to place on Saturday means he either needs to re-engage or continue to slip further, I don't know if that'll hold true throughout the week.
Nobody is right now while point losses from failed attacks and defenses are in the system. If defense rate didn't matter, that could change.
