What you posted is a great indication of exactly what I'm talking about. Yes, you need cover, but how is it accomplished on those maps? A rock, a stack of wood, large containers? None of those (except Harvest, which is more similar to Coldfront than the others and thus not applicable) utilize walls on the point itself. The point is a high traffic area that should have the most combat, so you want it free from obstructions if at all possible (in this case anyway). I don't know what you could do because I'm not sure what your theme is, but I would look into other options.
