Decrease odds of getting a painting on a star casino machine, or increase other item drop rates. (can undo after at least 7 more people join) Small deflation of currency (when people join back economics will inflate again) Set up spawn egg shops (as we can't get them because no one is around to sell them) Set up enchanted tool shops (see 3) Allow players in main to pay players in SkyBlock (in case of debts to players in SkyBlock)
I like that you want try to revamp the main server, but... The starcasino is meant to be similar to an actual slot machine. The prizes are high in value, so having the ability to get nothing often is on purpose (the cheapest prize, 25k in ECD, is about 80 - 100 nstars in value and the most expensive prize can be sold for almost a million ECD). The Starcasino in Skyblock has the ability to win a prize every draw for the SkyGod rank, but still, that's the highest rank and the prizes are so much more cheap compared to the Main Server's Starcasino The economy basically governs itself. Staff cannot really deflate the currency as the players themselves take care of inflation and deflation (When Star Crates were introduced, it crashed the Star Market, and it really didn't recover) We have egg crates as our spawn egg shop, plus there are a few that you can buy at the Spawn Shop for Exp. We basically have this already at the Spawn Shop. Plus people sell enchanted items still. For Example: https://www.ecocitycraft.com/forum/threads/lots-of-enchanted-crap-for-sale.172540/#post-959955 The rate of Main Server ECD and Skyblock ECD is drastically different (meaning one ECD on the Main does not equal one ECD in Skyblock). I see more problems and abuse than actual benefits for this.
As Jdawger outlined, Main Server ECD and Skyblock ECD aren't equivalent. The current exchange rate via the forum bank is 15:1 and that money can't be returned to the main server. You could pretty much ruin someone's business by, say, loaning 3 million ECD on the main server and returning it to them via Skyblock (which would convert to 200k SB-ECD), therefore effectively destroying their main server loaning business. (For the other points, see Jdawger's answer.)
