Reworking some omni city to better is good idea, in my mind what must be included:
1) Grid
2) Whompas maybe Jobe too
3) Daily agency
4) Tower Shop
5) It should be tight and clear zone like Borealis or Newland City.
Genearly all major OT cities are a mess Rome, Ent, Trade and HQ. I have to check what would be good one, if there is one...
EDIT: What comes to mind is either Lush Fields Resorts or 20k. Still, would need lower level mob population around those zones... Lush Fields is quite nice there is room to add more buildings and doors there I think.
So, where do orgs get credits after this? Allow new taxation options? Like cut from mobs credit drops?
