Was talking to a few GAFers in game, and really think bungie needs a public bounty system.
Stay with me, I know it sounds a little weird, but it will make sense.
First, have it where you can talk to the bounty dealer, and have an option to go into your inventory and select an item, or number of them, and then select a requested amount of another item for trade.
Example:
I place a legendary Scout rifle in the bounty list, and then pull from a list of possible objectives that would be a fair trade, say, 200 Spinmetal, 200 Spirit Bloom, 200 Relic Iron, and 200 Helium Filaments.
You can not place a title, and the reward will only show its rarity by color to other players looking at the bounty.
People can judge by the amount needed to get the item, that it is indeed rare, or that is is worth the grind.
The number of items and in what quantity is just place holding, but I think this would make for incentive to farm, and also make it hard to abuse the system as well.
Thoughts?
