This is a strategy that is geared towards Chanthery/Edine and beyond parties, and requires 1 Knight and 1 Mage. (healer HIGHLY reccommended)
It's pretty simple, basically, when there's aggros scattered around, attacking random party members, the Knight uses Wild Swing to bring in all the aggros to one spot. Then, the mage uses Frost to slow all of them down, leaving a small but possibly life-saving timeframe to escape a mob which could otherwise kill off your whole party.
