I find the higher-grade, rarer favor materials (such as Heavensnut, Swordleaf, and the like) to be useless for me, because I prefer spending less per one i170 material (Adamantite Ingot, Griffin Leather, etc.) rather than 3 tokens for 5 HQ base material. I'm just interested in a trade system to trade 1 rarer material for 2 common materials.

It's similar to the system where we were able to trade in NQ 4* book materials (Intricate Silver Brocade, Water-hardened Hippogryph Strap, etc.) for 1 Fieldcraft III. Though it was added later, I'll give them that, but I'd like to have this available earlier in the system because at the moment, the only people who are going after these materials which take 3 tokens per set of 5, are those who cannot exactly guarantee 100% HQ with NQ mats.

I dunno, is it just me who wants this system? Because, on Shiva, there are more entries for the rarer materials than there are the common materials.
