The upgrades for this thing get exponentially worse cost wise. For example consider the upgrade from lvl 4 to lvl 5. A million elixer is worth 1200 gems but the production increase is.only 3 gems per day. so if you divide 1200 gems by .3 you get 3600 days to get back the 1 million elixer. Lol so it would take like a decade of collecting to catch back up. That's kind of funny.
