I mean... Swindle World would be pretty "unbalanced" as stronger players will just bully weaker players. :> But it would potentially help lower the game-economy. Certain items are a tad bit expensive for no reason.
I think it will be released soon enough. Probably 1 or 2 more level cap increases and it will be balanced enough. only other option would be to overhaul certain events just to nerf them for now.
