There should be a /sell shop for Prestige 4 as to provide an incentive to +++'s to keep playing. Perhaps after prestige4 there is a 1B$ rankup to "Z", when I do /ranks I see Z but idk if it's actually a rank. Maybe after Prestige++++ its a $1B rankup to Z for the last shop
I'm honestly not quite sure why the server has a limit to the number of ranks. Could there not just be infinite ranks following a formula so they get exponentially harder as you go up? That way nobody would ever reach a point where they had no reason to play anymore. I think this would ensure that everyone has some reason to make more money. I don't think there should be infinite shops though. Maybe prestige+++ or prestige++++ should be the last shop, and then after that you just farm to get the tag in chat or maybe some perks. Otherwise people would start getting crazy amounts of money for the same amount of crops, and that might break the player economy. By the way, I don't think "Z" is actually a rank.
We are already looking at fixing the sell shop for higher ranks and finding a way for people to keep grinding after Prestige++++.
