Best solution = remove them.
They are useless
If splash damage from HE, artillery, mortars, rockets, and bombs would put soldiers in downed state more than outright killing them, then maybe medics would make just a little more sense, but that would maybe change too much about the game? Also, if flame-damage would be such as to more like suppress a bit more than it damages, that would also be jobs for medic class. Well, perhaps it’s pointless, I don’t know?
Medics need something, like a passive healing radius. Similar to the Proximity XP multipliers suggested in earlier threads.
At the end of the day its a game, and we need some “gamey” features to make all roles viable and interesting.
Imagine medics could revive like in Battlefield games. That could be “interesting” or rather potentially OP.
medic squad should be expanded by 2 , 1 at or 1 engineer or 1mg or 1 sniper
