It is one of those deep questions really, do you buy 15K for others to look at or for your own personal satisfaction?
Like take the 15K monk headpiece for instance, if your monnk has hair and nobody is ever going to see the tatoos, will you just scrimp and buy the 1.5K versions instead?
I bought the 15k for My warrior back before the hidden feature was added its the only one i let show because LT helms and Drok Hammer Halms dont look that great
