The Dragon Slayer's roar was the strongest status effect, mainly because of its wide range, which would buff an entire city. If Lu Li handed in the quest, then everyone in Stormwind would receive this status. Correspondingly, if Glory Capital completed the quest, then only the players who were Orgrimmar at the time could benefit from it.
Secondly, the status effect had a longer period of three days. Many things could be done in three days, so Lu Li didn't rush to hand in this quest. Everyone had not been able to finish the Instance Dungeon of Onyxia's Lair yet.
However, he couldn't delay it for too long. Now, Lu Li was planning to use the three-day status effect bonus to complete Blackwing's Nest.
