I acutally chain Easy Preys. They do pettiful dmg against you and i can gain 18-36 exp whereas in EMs i have to get 100exp, then stay down and rest. Whereas with WHM sub i can kill alot of EPs with red hp, cure a few, kill more, then rest. I feel its more efficient in that sense. That and WHMs cant take EMs and BLMs can risk dying using all their MP..from my experience.
