Players should be able to see H/H drops assigned to them, and if possible, buy over their loot, maybe at say, 5~10 X the normal sale price, when they pick up the H/H loot.
Pros:
- Helps to improve the quality of drops artifically.
- Improves the odds of players who are intentionally hunting for specific items, like gold/green/trophies, especially for certain bosses types which are hard to solo.
- Does not help RMT traders or focus gold farmers, as the price attached to the H/H loot, may affect overall earnings. (Heck, if they use Bots to farm, imagine them picking all the H/H loot, which might instead let them end up with a net loss

All in all, this is highly beneficial to the casual players who like to solo quite a bit, but are not as skilled as to do 1/2 party farming and have to make due with using H/H.
Edit:
If u all are so afraid that the "elites" lose out on value of certain items like ectos and dyes, just simply tie in the prices of those with what they are worth at the NPC merchants, probably at 90~95% of the npc value, so that they can profit, but probably to a lesser extent. ( Ectos at 5 k, black dyes at 6 k etc etc. )
Prices of other items are gold/collectors/unqiues/trophies, can be scaled up or down accordingly to whats acceptable. Just having the option and the ability itself to buy over H/H items is good, as it offers the casual solo players another way to get items, rather then sitting 5 hours infront of a monitor, waiting for players in a town to sell something he is haggling over.
Final Notes: Contrary to belief, they ARE some players out there who are more "lucky" or "unlucky" in real life, what I mentioned for this idea, actually helps them out a little bit.
