Hm i wasnt very clear there.
By map frame i mean mountains at map borders like on Goodlands, Darkfall, Broken Vow etc. It feels like playable area was brutally shoved into a square. The frame has no terrain and crazy elevation that both do not fit imo. Zlo has a good point about limiting area for map balance purposes but im not talking about that at all. My concern is mostly aesthetics, some really good examples are EOTS, Last Oasis, Pizza. It feels like part of the map there, and is really cool and natural.
