Hi this is my first time posting I have searched and haven't found anything like this so this is what I've been doing.
When you go to Throne of Tides with a hunter go up the elevator.
From there you will go into a hallway and fight the first 2 wave of mobs.
They drop rare and uncommon items and also drop 50-2g a drop it takes me about 1 min to kill 4 guys.
Once the four guys are dead and looted feign death near the entrance and it will reset those 4 mobs. it takes about 15-30 seconds for them to respawn rinse and repeat.
I find this exploiting because your abusing their respawn rate without resetting the instance.
I hope this is helpful. This will work with any class with a vanish ability etc etc..
