I would like to suggest changing the black market refreshing every 3 hours to instead give the player the amount of refreshes during the day as free attempts. Example: If the shop first starts refreshing since 8:00 then 11:00, 14:00, 17:00, 20:00, 23:00 server time respectively, instead they should give the players a total of 6 free attempt to refresh black market whenever they want, everyday. I mean not everyone has free time to be checking the shop every 3 hours, this option saves time and help players not to miss out any good items.
