It's possible he didn't even know he was NEEDING on the stuff. Seriously when the loot dialog comes up its 3 buttons.. NONE say NEED, GREED, or CANCEL.. They all have funky icons and the first few times I ran dungeons I just hit the first button without knowing it was a NEED roll. When I figured it out I gave the loot to who needed it but this is going to be a big problem because the first button is the NEED... then the GREED, then the CANCEL button... all have different icons so its up to the players to figure them out!!!!
