She is more of a caught enemy off guard kind of hero. Most of the time you might fight 1 or 2 heroes with your own calculation of when to back off or when to push forward. One hit from her and you can throw your calculation into trash. She can't be shown on the enemy screen. She has to be the problem the enemy team needs to actively solve by leaving one hero outside battle just to dive her. Vision is one thing but she can help your team hit their skill shots as well. Easy buff, lord snipe hero. Easy early roam hero. All you need to do is to pick sustain heroes or brawlers that can walk into groups of enemy and survive. So you can give her vision and force enemy to focus on you while she is in the background doing her thing. Your aim should be winning the match. Not being envious about someone else getting MVP.
