I decided that I didn't like the plain white of my HQ Goldsmith Body and Trousers and decided to dye them Ceruleum Blue. After successfully dying the gear, I noticed that they were now both Normal quality ceruleum blue pieces. That had lost HQ status.
Is this the normal for dying HQ gear? The in game help says that gear can be dyed over and over and the color removed but nothing about dye removing the bonus of HQ.
