As discussed in the CW Forum, there could be some planets with a special map or an additional game mode in the queue for 12vs12 premades.
A big amount of players want some warfare in much bigger maps, so as CW is officially in BETA for testing, so you could create a large map with big cunks of existing maps for fast work. Fill the gaps with interessenting geometry and don’t be too tentative for using low res/repeating skins of new areas.
So I created a large map of existing ones with following ideas:

Time: 45 Minutes
Winning conditions :
Gain X points (maybe 2000) before end of time or more points than the enemy
Attacker and Defender owns about one half of a map. Each one have a base. There is a neutral one in the middle of the map.
To score:
- Destroying 90% of all enemy turrets and b6uildings will give you 2000 points total
- Capturing like in Conquest mode with much bigger areas to gain points. But you have to be there with 4+ Mechs to start conquesting. After conquering the area, 2 attacking Mechs have to remain there to secure scoring. To stop conquering the area, you have to get in with 2+ Mechs. To conquer it for yourself you need 4+ Mechs and max one enemy remaining in the area (not enough to stop conquering
Tactics:
Pure capture will leave you in the position to let the enemy destroy your objectives.
Pure destruction is a long distance to move.
But both is possible. Because of the map and possibilites a mixture would get the goal.
It would be a cheap way to see how the community will interact with a large map without creating too much new content to test it.
