I don't have any opinions on what levels should be used... but if there is a contest I'll definitely make a CTF level to submit to it. Although that's maybe more appropriate for a future tournament mappool, rather than the one for the ladder (which seems to favour old, proven classics over new levels). But that's up to the people running it, really.

Or, I could just make a new 2vs2 level anyway. I like contests though, because there's more competition, more motivation, and a higher chance of the levels getting played.
