Gp is a naff metric and meaningless. Top 40 gp is closer to the mark is cg wanted to be stingy.
Better would be if you both got credited as a win. You’d lose the bottom place position, but as draws are rare it would be infrequent, but everyone in the group would be happy with the outcome.
If there are more matches to play, the high gp player could then face the winner opponent and the low gp player face the losing opponent. The effect could cascade too so it could work regardless of which round it occurred in and how many draws occurred.
Granted it would be an in built method for gaining the system which some would use, however given that cheaters are rarely punished, and their victims never compensated as cg promised in the early announcements for gac, I don’t thinks it’s a huge issue. Cg obviously would disagree on every aspect of that of course.
