Lightning Whip (Elementist, Main Hand, Dagger Skill Slot 1) can’t hit game object half the time, you always have to reposition yourself and even so most of the time you get “miss” even though you are right in front of the object.
This doesn’t seem to happen while attacking.
Also, Lightning Whip should Hit monsters in front of you since it basically pass through them, much like Vapor Blade in the Water Attunement which hit all the monsters it pass through.
