Instead of punishing people for trying to get the loot they want, how about eliminate the reason this happens. People prioritize the loot they want, so they wait for a bolt to be rolled on before rolling on anything else. How about letting people roll on everything, if you win the roll on multiple loot, the game lets you choose which one you want. The piece you don't choose, goes to 2nd highest roll. This way people can roll on everything without fear of missing out on their top priority.
