This is my first suggestion to the really well balanced game!
So its true the medics do alot already, but they are both equipped with snipers. the snipers add hit modifiers that allow the team to do more damage. to me a snipers “skill trait” is aiming really well. so my suggestion is this. add a 2x and 3x multiplier for those eagle eye snipers out there. in my mind its going to me NEAR IMPOSSIBLE to hit those small markers twice in a row on a normal rampaging monster. so if a gifted or lucky sniper can hit it twice. that marker will change color to indicate that all damage on that spot does Double damage or 2x the amp(so one shot is 1.3 damage. 2 shots would be 1.6). For laz maybe a smaller multiplier since he has a really fast rifle.
Thanks for reading and keep up the good work!
