I'd suggest reading the community guidelines.

I really like the idea of moving quests away from "here are 1-3 items, please bring them back, here is a formulated reward based on the rarity and user price of those items". I'd love for original concepts for the quests, ways that we can make them unique and have unique prizes based on those requests.

It's hard, though, because the reason we switched to QP instead of having each questgiver have a pool of items, is those items get devalued so quickly. Maybe if we had special pools of prizes but you only had 2 or 3 quests per day from some of them (Sagg, for example) would mean way less of those items going out (especially if we lightly weighted them).

Like would you feel better about doing a quest if you only had 5 per day (a few more if a GA) from each quest-giver, but the prizes felt more substantial? We've obviously done this before when we lowered the number of quests from 30 to 10, and I think that went over pretty well.

[edit]

I've basically done that today, there is now a minimum amount that you'll get from him. I don't think that you should be able to just know and make a profit on every quest, though.
