Is gryphonskin armor recipe for bard correct?

Sorry if someone already asked this question already. Why is the gryphonskin armor for bard cost twice as much in the special materials?? ie animal fat, potash... than the other comparable pieces?? Only the body cost 1 hard hippogryph, rest need 2 or combination of hard hippogryph and vanya silk! I didn't look at all the other pieces but the ones I did look only needs 1 leather or vanya silk or darksteel ingot, is this correct?? :confused:

It's been a known problem ever since the last "hotfix" -.-. Some pieces are totally not worth crafting now. Vanya Breeches cost 2 hard hypogryph leather AND a vanya silk....

its a carry over from 1.0. any tier 2 items that only requires 1 tier 2 mat was in 1.0 because that's how much was needed back then. new ones in ARR requires 2 at most.
