The spirit of the question is, how can one change the payout system to incentivize going for wins and discourage conservative "draw play". In FIDE chess, they have experimented with (gone to?) giving 1.5

for wins and .5

for draws. This encourages players to gamble a bit more if the game is close, rather than playing to "not lose" to stay in the running for first.
So.... with that in mind, surely this creative group could come up with something that would move us from the current behavior, which I assume all believe is imperfect, to something closer to perfect?
I'll throw out the first example, but focus the energies on brainstorming better variants, not just beating up this straw man: If you are in a draw, you LOSE points. Or..a 5 player draw, lose 90% of your points, a 4 player draw, lose 60% of your points.... the concept being, you don't settle for a draw until there is no possible superior outcome.
Or...if it is argued that that is what the behavior is today, then....1st place gets 70% of the points, 2nd place gets 30% of the points (I know that's not WTA), but this means that it may be better to fight for 2nd than accept a 4 way draw... Just think about what behavior would be desirable...
