Great Elder turtles found on the west side of the island have 2 abilities: aoe knockback and frontal cone attack for large damage
It's possible to kite the Great Elder turtles all the way to celestial court
If you're a dk you can use path of frost to move on top of the water and kite 2-3 of them over there. Make sure you taunt and keep some dmg on them or else they will evade.
Bring them into the group of players that are near the quest npcs or into a ongoing world boss kill
Hilarity ensues
Enjoy
Quick update:
This works for mobs east of the pirate ship as well.
You can pull a molten guardian and the latter into large crowds that are either camping or doing ship
