There is no ninja looting in need/greed system. Hell for the most part everyone just passes on the new dungeon gear. Also as a DPS, roulette queues haven't been anywhere near 30 mins. More like 5. Only things that have long waits are CT and older content all together, but that is not just an issue of tank shortage. People just don't want to do them.
