Half the time, I have a hard enough time managing mob packs as it is. Especially in Bardam's Mettle onwards where they start hitting like trucks and I don't have the greatest gear. If you grab an additional enemy you will tank it alone and I'll be sure to not hit it with any aoe skills.

Like it's one thing if I have an all mage party. I'll pull whole rooms then; but two melees, especially 2 DRGs? Nah. You're getting packs daisy chained and you'll learn to like it!
