I'm a supporter of adding newly made maps, so I'm fine with adding Rogues River, but why Archers Valley and Altair Crossing? One of them has trees blocking everything and both of them have very artificial hills that path and look weird.
A new map that isn't too large and hasn't had MM time yet (afaik), is Incandescence
. (Also offers interesting graphics compared to all the grass maps).
As a replacement for Altair Crossing/Living Lands, which I suppose has to be a small map, we could have a vote between a few older maps.
