So I think what they could do to implement medics in the older campaigns is by converting one of the assault squads into a medic squad.
They can just directly add it since there will not have separated campaigns in the future. You will just have 1 squad pool for each nation.
For replacement, one major problem is medics are not possible to carry secondary weapons or backpacks, so how are devs going to exchange or compensate for that? At this stage, I think it would be more efficient to think about how to implement it in the new national techtree system, rather than waste time on this controversial economic-related problem in the existing system.
Campaigns will be merged in few months + squads will be completely redesigned soon. I don’t know what’s the point of this suggestion imho. Just wait.
Why would you want medics over regular assaulters? What I hate about medics is that they cannot have a backpack slot so no ammo pouches which is why I prefer regular assaulter over medics.
I ended up buying a premium assaulter squad in Stalingrad because I don’t want to stick with medics that couldn’t carry much ammo.
With medics, you can have up to 5 men carrying smgs in your assaulter squads (4 assaulters, 1 medic) + ai medic can heal you from time to time. In campaign without medic, you can have only 4 men carrying smgs in assaulter squads.
So medics are definitely useful. 
5 men SMG squad? There’s this one while my regular assaulter squads have 4 SMG, 1 MG and 2 rifles
No time to stop and heal most of the time plus that medic would’ve been dead easily with my playstyle of being aggressive. Other than that, very situational where most of the time you would be dead before being able to use medkits one reason why I chose ammo pouches over backpacks.
Oh yes. Medics would help. Few people play medic the way they should. And the truth is that if someone plays only as a support, he can save the attacking team a lot of reserve points.
like 50% enlisted matches is defense where attackers don’t even try to cap.
to not lose mind with boredom you can either spawn camp enemy, role play as sniper, dig some trenches or get medic squad and run around heling people
i’m actually looking forward to having medics in all campaign, already got my squads prepared
if attackers just sit on grey zone, my options are tanks, HMGs, snipers and sometimes planes depending on the map.
Medics better not mess up some squad compositions like a medic replacing an AT soldier slot for engineer squads instead of having the choice to have 2 AT soldiers in the squad or flamethrower squads with one assaulter being replaced by a medic.
Are you really comparing premium squads with normal ones? Jokes on you, someone is trying too hard.
Btw My female medic squad is superior to your boring “another ppsh reskin” guys, boobies rules.
No
No point in that, Campaigns are merged soon.
why medic squads are basically assault smg squads with extra healing abilities anyway? no need to turn all of them into Desmons Doss but rifle or just sidearm is more fair
