1. When tanking, try to get in a position where your mobs and allies are in front of you, and nothing in back of you.
In this way, if an enemy attempts to use an AOE cone attack on you, only you will have to dodge/stun and your partners
will remain safe.

2.The less amount of enemies you take at a time, the better. If you see a group of enemies if front you (that don't have that linked aggro line),
try to use Shield Lob to lure one or two enemies from the group. You'll be easily able to kill them without stressing everyone else and/or being overwhelmed.
