The game is transitioning from simple, elegant formulas into complex ad hoc ones in order to do small alliance tweaks. Building cost, ghost acres, DR times. Speaking of DR and the half-life again, I don't have any big issues with the half-life times being what they are (besides it makes things more complicated) but it's bad that it's not displayed anywhere. TPA put up a site that had some estimated DRs but it's down a lot and doesn't always work. That change could be OK but it's bad instead, because it's way too much work to figure out what DRs are.
