The land should be in the "low lag" areas, like Mort. (I am sure once a few towers are placed, and a few teams of defenders and a few teams of attackers are there it will get nasty.)
This would mean mostly desert areas. There are a lot of places where no one goes, as there is little to see, these should be prime land areas.
I just hope the towers have some sort of remote warping beacon so a team could get there quickly (for those who are yalmless).
And maybe a few new areas (maybe only accessable from the grid) just for land control.
