This is the one thing that people who get upset about Sparks and snipers in general (in all games) don’t quite get. I move very erratically when I know I am going to be in an area that might have a sparks/vassili. Weird moves towards walls, zigzags that aren’t consistent, wall jumping as much as possible. All of which not just keeps you alive but opens them up for return fire since they have to remain exposed to try and shoot you. Which then allows you to more easily close in on an 80HP merc. If people see a video of it they probably don’t think much of it or think you’re just not very good at movement when in reality you’re doing A LOT to avoid any chances of walking around a corner and dying.
I think Sparks and her Revivr is perfectly fine the way it is. Especially now that revives got toned down slightly in the last patch.
