This works best for consoles cause well, not many people know about it. (Also we get later patches so it'll probably be awhile)
Step 1) Have another friend for maximum efficiency. Although you can have as many people as you want (up to max I believe, and it still drops items for ALL members)
Step 2) Go to this spot:
Step 3) Have a Restoration / Lightning Staff and position yourself either on the fence gates or the stairs -- Make sure your crosshair is aimed in the middle where you are able to automatically hit both of the mobs. Tell your friend to do the same.
Step 4) Get a rubber band and tie it to your Trigger button
Step 5) Have fun farming!
P.S
White Meat
Additional info: Only 2 pigs will spawn at a time, so you have to keep killing the two on one side to spawn the 2 on the opposite side. That's why it's best to have a partner.
