1. Yes, a well played game will end in a draw. But that does not mean that a game that ends in a draw is a well played game. WTA games where three players go for a 3 way draw is no better than PPSC games where two players go for a win and strong second. Either way it is point/rating farming and not actually playing to win. In my opinion.
2. I had two proposals that have been proposed by others in the past.
A 0

game that doesn't count against stats or ghost rating or anything. No fear of being eliminated, no reason to not go for it.
A WTA option where a draw results in all non-CD players getting their points back, even the eliminated. GR would presumably be similarly adjusted for this WTA option. The point being that "going for the Draw" is pointless, so go for the WIN or bust.
3. Rage is Therapy II, basically was a 3 way draw between 7 players. 3 players were the western triple, 3 were the southern triple, and then there was small Russia balancing the two. Neither set of triple could self implode without giving ground to the other triple. So really it was very little different from a 16-16-2 three way draw.
