I think (and I have no idea how feasable this is) that they should change the way RNG works on these loot drops, making it so that there is a higher chance for loot to drop based on the current party composition, and a lower chance (obviously it still needs to be able to drop) for gear to drop that is not equippable by anyone in the party. It could go even further and check current ilvl, but this is unnecessary.

Or... I guess tokens..... (but I hate tokens, so much inventory bloat)
