How is everybody using Lion's ability to get the most out of him?

Title

What are the best ways so far that anyone here has found to use his ability? Personally, I've found it good to pop in the middle of a scuffle to either slow or see any enemy rotations. I've also found it to be good in conjunction with a normal drone, as you can find the enemy, and then use his ability. If they don't move, then you know where they are.

What are everyone's thoughts?
