that is ridiculous
we get the building 4 times more often than the upgrade kit (not exactly. average value from postings above)
and we get the buildings more often (relics, earlier levels maybe)
so for one upgrade kit I will get 10 buildings
damn it. put selection kits in there
They likely want people not running out of potential chase items with the upgrades so don't want to award them too often. They also likely want it to be 'easy' to have a base for the upgrade for new players who don't have years of GE crap already.
I agree it's a bit disappointing, but it seems strictly speaking better than before. So not a lot to complain about. Just also not a lot to be hyped about.
