There are a lot of outdated MMO "loot etiquette" rules floating around, and what you brought up is one of them, OP. If the player participated in the kill, they are allowed to roll need on anything that they are eligible for. Your perceived need is not greater than another's, regardless of what they intend to use it for. Now if this is unacceptable, blame should be forwarded to S-E for allowing the same token to be exchanged for gear and items that can be sold on the market board.
