i think they should do this honestly
75 bucks a year for a dev server
have a option when u purchase saying u can add slots to invite your buddy's to work on the project
3 slots -10 dollars
5-slots 17 dollars
8-slots 25 dollars
these slots will make it where theese people dont have to buy gold
and make them where u can change them out once a month or whatever with a command from owner account
so that way everybody is happy and unximad still get his money
