I do raid ICC10/25:

So I got the belts, because they were a huge upgrade over my Nax25 belts. Since then, I have sold 3 Primordial Saronite per toon. A little extra gold buffer is nice, especially if I can't replace my toc5 dagger reasonably soon. if the price of hilts drops a little more, I will be picking some of them off the AH; essentially buying Hilts with Frost badges.

IDK how soon I will begin investing in T10, perhaps once I drop out of the top 5 DPS done in ICC25...
