When will the Mantis nerf be coming out ?

This game is starting to become annoying when running solo. It’s fun don’t get me wrong and this is just about my only complaint with the game so far. Just running into a stack every time that has Mantis and she just instantly heals all of her teammates with her ult and im sitting here for 3+ minutes getting mobbed by their whole team with blue overshield and they just dont die. The attack buff you get the with her ult is insane too. Her movement is so good too, you can just jump around any enemy that has no long ranged attacks and pick their health apart.
