I play on Xbox, and I see Medic Squads moving up with the groups that are attacking. All 3 medics in the group are going crazy keeping everyone topped off on health.
Medics would be awesome!
I dont think it would be too difficult to alter squad skill trees to make this a reality.
However, i do think the number of medics should be limited to 1 per squad (outside of a dedicated medic squad ofc), and revives have a cooldown timer so that it doesnt mess with the balancing of the maps too much.
