I agree, I've been saying for a long time that the format of the round-robin needs to be changed.
Double elimination for 8 players, best-of-3 in the upper bracket and best-of-1 in the lower bracket. Grand final best-of-5. The time frame might be the same, but it would require less player commitment.
+1. If a round-robin is played, it should only be as a qualifying stage - for example, 4 players advance from the group and play a mini-double elimination with a grand final. A tournament with a bunch of meaningless games and no grand final doesn't qualify as a top-tier tournament.
