Well, isn't it likely that players will find good positions on any map you make? Are you guys confident that a map can be made that will be truly, utterly and perfectly fair?
Utterly and perfectly? Perhaps not. But these trends are not as strong on Colonies, AT, and SI as they are on the new BT, EC, FEI, and Dwi.
A larger (and rounder) map, with less major geographic barriers, and a possibility to set up cities anywhere, would greatly lessen the deterministic effect of geography.
My previous suggestion, a few posts above, of portal regions would also be a good element to counter the impact of geography, by partly nullifying the edge effect.
