One shot mechs - Please make more apparent

Happy to get hit and die when i stand in these............. If the screen lets me know where to stand to avoid them, its not always clear in your game.
EG Act 3 cruel boss I didn't know to be close or far for the hover mech the wind looks great on screen. However, not a very good indication if i'm in a bad or good location.
Red is a great indicator of GTFO
