Rare? Well any that I have been able to get are likely not that rare. I would assume the low percentage stuff then. KF Raid gear-Ascendent or Bonemarrow Crimson Doubles or SRL due to limited release VoG or CE shaders (Crypto/Glowhoo and Chatterwhite) are probably getting more rare as we go due to non-interest for much of Y2 players (except the NTTE quest anyway). Same for Queen's Web from Skolas. Beltane maybe, cause I hear lots of ppl say they care less about getting all 50 calcified. I actually like that one.
