First unlock the daily "Defending Wyrmrest Temple" Min Level 71
It's a long chain
Kill the Dragons and Destabilize the Azure Dragonshrine
Once you Finish that on the 4 platforms around it there are 4 mobs on each
They are humanoids but for some reason the dragon can attack and kill them and around 1k-2k xp a kill while there is about 16 mobs with a pretty quick respawn rate
So what i do is kill the mobs first then complete quest while they are all respawned again
20k from quest, and about 15k-32k just from killing the mobs which are killed 1 shot and can be done every day!
I know it's not the greatest find but i think it is very helpful while you are doing this quest
