Yup, shockwave's great for flipping a guardian's shields for an easy headshot bu that's literally all it's good for.Rank 1 can occasionally be useful for staggering stuff. Sometimes handy against Guardians as a Human Vanguard. At least it staggers more than in the demo.
I have a question, why do I see people casting the engineer's combat drone halfway across the map when the most I can mange is about a foot in front of me. Is there a trick to it I haven't mastered?
