I support a character re-customization option as well. I have played some other games recently that have a similar system to the gem store, they typically do one of two things; you can purchase a character re-customization token for a fair amount of ‘gems’ or using in-game currency like gold, silver, or copper to purchase character re-customization from a local shop (usually this option would cost a smaller amount). I typically prefer the second option since it is usually cheaper and allows players to make customization to their characters more often.
