I had a few cases where the Conduit Storm has stopped attacking, not doing any damage.
You still could hear the attacking sound but only the half of it, it felt like the storm was staggered.
After watching the replay i came to the conclusion that it has something to do with the heavy cover system - i did click the storm on the enemy wraithguards walking away into their shield generator (the shield was allready completed).
At first the storm worked as intended, lighting strikes came down and the enemy units got slowed., The first 2 strikes didn't hit the wraithguards because they were walking in a straight line away from a storm, the 3rd did surprisingly finally hit (big wow!) and then the wraithguards reached their heavy cover bubble within the shield gen. This was the point the conduit started to act really weird: As i said before you only could hear the half of the attacking sound and no dmg neither lighting did happen.
Finally a completely wasted "super"ability. This happens quite a lot
Note: The conduit damage on objectives like base turrets and shield gens is INSANELY decreased and i won't even bother to try to hit any objectives ever again.
