Midfield is usually the ideal place, unless rspeeds are too high, then one of the bases is fine. Place yellow armor as well as red armor in the spawns, the code will change and if you do not offer all of these then your map may become out of date and need to be remade for a new version General Design Create your map around a solid design. WFA plays optimal with 16 players but there are many 18 and 20 player servers. Also note that most clan matches are 6 v 6. Scalability means that neither offensive nor defensive play becomes too easy or too hard just because the number of players is high or low.
Scalability means that there is ample ammunition in the spawn rooms.
No task should be overly complex to achieve as a team on your map. A button to open a door is about as complex as playable gameplay needs to be. Do not create one way glass that cannot also be fired into unless access to this area is common. Know all the classes of WF and what they can or 'will' be able to do. The best maps will be those which can adapt themselves to the new gameplay without major changes.
