I'd like to see the "Squad Revive" feature from Battlefield implemented, where squad members can revive each other without needing the Medic class. This could be complemented by the much-requested "dragging downed teammates" mechanic. For example, teammates could be automatically revived after being held down for 10 seconds, or, for something much more immersive, an auto-injector could appear in your vest when you grab a teammate, which you then have to physically use on them. The time it takes to revive teammates should be slower than if you were a medic. This way, if the squad's medic is killed, they don't have to rely on others or wait for them to respawn. For example, in a sniper duo separated from the rest of the squad, if one is killed, their partner could assist them.
