Aight so after a few playtests I think I've caught the major issues. As ithilis said I might need to nerf airslot a bit, but that remains to be seen. There are a few higtmapissues to be sorted out.
1) Making the islands a bit bigger so transports can drop without issues.
2) Fixing the higtmaps in the back so engies can't stroll off the plateau.
3) Flattening the area around the sideplayerbases so that players can build without to many issues and terraforming.
beyond that I'm thinking of reducing the amount of mass in the middle so something not to silly. Any recs on the amount of mass that should be left there? I'm thinking in the 2-3k region but might cut it even further in the future.
Thanks for all the feedback guys! Makes it more fun to make maps when I get feedback
