Maps like this would be preferred:
1) Good enough to have in a league.
2) Provides great clan play ( that is: Renan may be a good map for public play, but it's NOT a good clan match map ).
3) Good FPS.
4) The developer is known ( if wee need to get any errors fixed to use it ).
A short explanation on what you like about it would also be great... this may actually be great info for anyone that likes to play user made maps
