Is there a reason that any style armor skin on the BLTC is only 1 time use and not something similar to Achievements skins?
If I drop 800 gems ($10) on a skin I would expect it to be account bound and be able to be reused at my will.
I also think people would be more inclined to purchase these said skins if they were reusable for the purchaser.
The way it is now just seems really wrong and expensive to me to charge for each use.
