One of the issues that come up every now and then is the cost of changing your looks and how it ties to the gemstore so that transmutation charges aren't going away.
Currently, changing a piece of armor's skin costs a charge, regardless, which makes changing your look a total no-go for characters that are levelling (players suggest you stick to outfits because of this).
I was wondering, what if there were an option in the wardrobe to "free" a skin, so that this specific skin no longer costs charges when being applied. This would, of course, have a cost. It could be a "wardrobe freedom ticket" which could cost.... let's say, 10 transmutation charges.
Is that too high? Then make those freedom tickets tradeable in the TP. I hear some players are drowning in charges and would love a way to make money out of that. Combine that with those players who love making alts and would love even more no longer worrying about charges for your levelling characters, and you've got a market.
Depending on how the market balances out, it's possible it wouldn't remove at all the demand for charges.
