May I suggest that you change this suggestion from removing the shop, to increasing the price of the OP items in the shop. As it is not only donors that use OP items. Money can also be aquire from voting, and possibly in the future, from winning. The shop will never be removed, the economy and donor perks revolve around the shop. Voting kind of does as well. If you keep this suggestion on its course, I do not support it.
Kinesy, Titans get 500 skybucks everyday. Considering that you get 15 dollars from voting every day, it would take about a month to equal the amount of money Titans get in 3 days.
I accept that however donators a what keep the server running and after donating $250 you can expect something pretty OP as a perk can't you? Also it's coming across that this is less of an anti shop but anti donor Rank perks, if there were no economy then people would not vote on skywars.
No support. I think all the items are perfectly fair in shop. Many of them are overpowered,but it does put a surprise and exciting factor to the game. I have won games against people who were using shop against me.
