Lu Li and Water Fairy were doing the Nether Drake quests not only for the Mount reward but also because the quests were easy and fun.
They would often get on their flying mounts when attacking their enemies to exercise their flying skills.
The time they spent in the game was happy. Even during the Stronghold War, Lu Li wasn't participating. Since there was no Fel Reavers knocking at the door, they could easily defend their Strongholds. Sky Moon even led an attack to take the second Stronghold in the Barrenlands from Gale Legion.
Seventh Heaven was the guild other than Ruling Sword that had a Fel Reaver but
unfortunately, they lost the second Stronghold in Hillsbrad Hills to Blood Red War Flag.
As such, anyone could see that this was actually a business deal. Blood Red War Flag now had two Strongholds in Hillsbrad Hills.
