My understanding is that there will be a minor sort of cash shop in ESO, with simple cosmetic items available for purchase, ranging from outfits to pets. I believe if a cash shop must be done, then it should be made so that there isn't a single item in the cash shop that you can't earn in-game with simple hard work. This way, the cash shop will be truly optional! If you want to lay down some cash instead of 'earning' whatever item you have your eye on, by all means... But for those of us that relish the ability to earn things, the cash shop should be optional.
Keep in mind before you comment or vote that this isn't a discussion on whether or not there should be a cash shop in the game. If there has to be a shop though, what kind of shop would you prefer it to be?
