AnEejit I agree with your overall point, and I think moving to 5 classes would already be a big improvement for Battlefield.
Right now, the main issue isn’t just the number of classes, but how one class is handling multiple roles — especially Support. The current Support class feels like it’s doing two jobs at once (ammo + healing), which makes it too self-sufficient and reduces the need for teamplay.
In my opinion, the best solution would be to go back to something closer to BF3/BF4:
Support focused on LMGs, ammo crate, C4, and fire support
Medic as a separate class again, with defibrillators, health bag, and healing tools
This alone would already fix a big part of the balance issues by clearly separating roles.
We would then have a much clearer class structure:
-Assault for more solo-oriented, aggressive players
-Medic focused on healing and revives
-Support for ammo resupply and suppressive fire
-Recon for spotting and long-range roles
-Engineer for anti-vehicle and repairs
Each class would have a clear identity, and no one would feel overloaded or overpowered.
Also, having 5 classes wouldn’t even be new to Battlefield. If I remember correctly, Battlefield 1942 already had 5 classes. So this wouldn’t be a radical change, but rather a return to something that has already worked well in the past.
On top of that, it could make sense to increase squad size to 5 players instead of 4. This would better match the class system and encourage stronger teamwork.
For those concerned about balance issues with adding a 5th class, I don’t think it would actually create problems. Right now, players who pick Support to be self-sufficient don’t revive teammates anyway — they already play for themselves.
The current system actually creates frustration because Support is seen as a Medic, even if players don’t play it that way. That’s why you often hear: “another Medic who doesn’t revive.”
By splitting the roles, players would have to choose between healing or ammo instead of having both. That alone would naturally rebalance things and improve teamplay.
Finally, for the Medic class, I think carbines would be the best fit as a signature weapon. They’re versatile, effective at multiple ranges, and suit a mobile, support-oriented playstyle.
Overall, this kind of system would bring back stronger class identity, better teamwork, and a more balanced experience without overcomplicating the game.
