I guess I'm lost as to what you mean by "storing units." They're already "stored." I'm not opposed to raising the values on some of the more useless GBs, after all Inno is not unknown to nerf the more powerful ones, but lets be honest here: No one ever twisted your arm into building Notre Dame, Colosseum, or any other GB. And no is forcing anyone to level them or keep them either. This topic tends to be repeated, as players seem to almost demand that some of these GBs "must" be improved, when its really been up to the player all along to invest in these virtually worthless GBs.
