If you're not going to increase the drop rate, then you need to decrease the required # of each. On Sylph there's a total of 32 HMPs up for sell... that would be 32/1500... That's completely ridiculous on the proportions of things needed. As for Riftdross, there's an amazing 0. That's right, Not a single one. That's a whopping 3060 of which won't/can't be turned in.
