Badosu, i agree, it could be great to have balanced unknwon maps.
But i think only Passes is a turtly map.
Lowland is a race to the map control and being able to keep it.
This Isthmus is really wide it is not more turtly than gulf especially with the map variant were there is random shaped land in both sea parts.
And some poeple loves turtly maps .
The best would be to chose the desired map pool to fit everybody.
