Not to mention, the Hawks can be controlled the same way our pet can (Attack, Follow, Assist, Passive, Defend, Aggressive, Move To). There’s already people testing and sharing their data online and it seems that in most cases using Summon Hawk x2 and then using Arcane Shot as soon as you can after the second Hawk cooldown ends is the best way to deal damage in single target (mainly boss) situations.
Honestly, the timing on that is super tight so maybe it can be manipulated at lvl 60 with a Tier Set bonus or something to make it easier, but that’s what I’ve been seeing online.
