my suggestion is to add new maps blockwars mode and also some great maps to have three or more teams Thanks
As Eastman mentioned, there are other gamemodes that need maps a lot more than blockwars, especially since blockwars has only just been released and most players are still getting used to the new maps. Also, I cannot see 3+ team maps being too popular amongst the community, given that blockwars and paintball are very similar in their objectives, and multi-team paintball is mostly abandoned.
You can make maps yourself. Besides, there are still maps back on The Chunk waiting to be migrated. Just be patient .
