Dude. You posted this thread waaaay too soon. There's still a WHOLE day left. Who knows what kind of awesome maps will be posted today. I joke, I joke. But my favorite map had to be Chromatic. Overall I'd say that it plays the best of any competitive/mlg map out there. I will go search for the link now. *scurries away into the dark corners of forgehub*
No, you're right. But I'm sure a handful of high quality maps will be recognized in the upcoming one, whenever that may be. But to answer your question...eh... R.I.P. is probably one of the most underrated competitive maps out there.
I loved Utah Mambo, and I still do. It's just plain awesome. I mean, an entire base geomerged into a large dune, before ghost merging! And it played great and got into matchmaking.
