As soon as I saw all these op greens on my Ah at the launch of BFA I bought them all up. Most of them I can't link in chat. I have not seen them on AH since I bought them all up either. There is one set of leather gloves that I am able to link in chat though and I do see them on AH sometimes still. The stats are the same as the one that I can't link but the IL is lower. Those seem to be more and more rare now too though.
