Guild Wars 2

How about if you buy a skin from the gem store it would be unlimited but to apply in-game found skin you would need those stones?

Personally i only buy outfit and not skins on the gem store because i hate having to rely on stones, even if i have more then enough to last a while.

With outfits, i can just switch to a style whenever i want too, why not to do so for store skins?

Although i am fine with the transmutation stone, Secret World does not require stone to switch skins. Instead, they have a price for a single character unlock and a price for account unlock (about 15% more).

I find this way better than the stones but that is just my opinion
