Honestly, I'm just a poor greenie who doesn't actually play that often, only votes for the rewards XD. So anyways, diamonds, and grass enter the economy very quickly, (3 diamonds per day for skygods) and up to 64 grass per day as well. How do spawners maintain such a low value (6-7 diamonds) if they can only enter the economy through extreme luck, or actually paying money?
This server has been on since around 2012, which is probably why there are a lot of Spawners around the economy. Also people have /kit Spawner every five days. You can also buy them on the website, etc.
Donor400s or people willing to spend $55 get /kit spawner - 1 spawner every 5 days. 73 spawners a year.
