My feeling is that maps like CCR and Inculta are prone to being very erratic in terms of how long 1v1 games run. One game can end in 3 minutes to a scorcher rush and then those two players have to wait half an hour plus for all the other games to finish. Not much fun.
If the tournament playerbase as a whole would prefer more maps of that kind I am willing to oblige. Given that CCR was not particularly popular in its last 1v1 MM appearance I do not think this is guaranteed.
(As for Valiant Saltscape... lol)
EDIT: A look through previous MM replays indicates that my assessment may have been unfair to at least CCR. I'll throw it in and see what happens.
