-objective
-not overly open.

certain races excel outside where others are better in close quarters... a map that offers both is a good... map should always have an objective as that prevents the camping/stealth races from overly camping.

dust, office, aztec, italy, prodigy... those are great examples of maps that work for both ends of the WCS

if there's a specific map you want and it follows those guidelines, just submit a add thread in the proper section and it will be reviewed.
