What an utterly horrible idea.
What about those of us getting the latest gear but off-set pieces? We run around looking like fucking clowns because you wanna set customization back by 10 years?
No thank you. If it's been earned, it is mine to utilize. If I want to transmog out of it and use the appearance of gear from 2 expansions ago, that's my choice. I never played this game to feel cool, and I couldn't care less about those that do.
