YOU NEED:
2 players ungrouped.
1 Mob that is aggro and would attack both players
What to do:
Player 1 waits near the mob they want to kill.
Player 2 runs past the mob catching the agro but neither getting hit nor attacking.
Player 1 attacks the mob before it hits Player 2
The mob stands there and does nothing until it's dead (then it falls over and gives you exp).
Player 1 gets exp and loot.
Rinse.
Lather.
Repeat.
