We could have a new feature which could be called "Criminal festival" or any other kind of name. In this feature players could buy limited edition mercenaries or gear that were held in the past. The festival could have a limited amount of things that you can buy at once and it could refresh every 24 hours or maybe every week. Also, players could pay diamonds to refresh if they don't like waiting. Give me your opinions about this idea and why you do/don't support it.
It would pretty much be a place where criminals meet up and sell their services or items and by criminals I mean "mercenaries".
