@svenni_badbwoi The main issue I can see can be fixed with moving props in the middle. I'm sure balancing the map could be optimised much better, but in the first instance I think making the props in the centre so they are vertically and horizontally symmetrical would make the map acceptable for use in the matchmaker pools. To avoid seriously changing the gameplay by changing mass values in the middle I guess that means four groups of trucks and the T1 MAA in the centre of the base, and the buildings laid out symmetrically.
Might be worth uploading a version 1 like that and working on more finetuning over time?
