Val needs LoS and common knowledge to heal hunters that are being focused.
Laz should either have players come to him for HB or get within range to use it.
Slim needs good positioning and good mitigation.
Emet needs to keep his buoys up and in a proximity where hunters are fighting. Strong mitigation also applies. A good Emet also should keep track of his teammates so when 1 is near a buoy, he can HB.
Caira is in an awkward situation since she needs to shoot and aim teammates to heal, but I’d say medics don’t require her skill of aiming to heal. Thus she is borderline UP
If you factor in the time it takes for the nade to fly through the air and land, she can’t be far away from players that need healing, but I’m not disagreeing.
My idea that I like a lot is to give her a regen effect to her Acceleration Field. This way it doesn’t OP her healing output with nades and allows for another form of healing. People seem to dislike my idea saying shes balanced the way she is… I dunno.
