Given the dubious results of the rotation/mixed BL poll. Before you do anything else with map rotations or polls about maps, leave Alpine in and bang out a quick map.
Draw a rectangle.
Gently rolling hills everywhere.
No cliffs.
Single choke points only. And just a few.
Slap some keeps and towers and camps on it.
Simple designs.
Some nice stonework. No wild Ausra or Charr architecture.
Put the Citadel in the middle for variety.
The Citadel doubles as the Garrison.
Outer Garrison can be captured.
Inner Citadel can’t.
Have a Beta with all three BL in play and see how we like it.
