I think it was nonesense to add the medic to the assault class. It would be really cool if we would have an extra medic class. The problem with the vanilla assault is that you don't really know if he can revive you if you need it etc. By splitting the class you would remove the assault's ability to heal himself which would make the class more balanced and people wouldn't stick to the assault that often. The assault can take grenade launchers instead of the medic stuff. Of course there would be a problem with the weapons. Well it would change the Weapons a bit. One could give the medic the carbines. This would lead to a conflict with the engineer but he could take the smgs and shotguns instead( the purpose of an engineer is destroying and repair vehicles so this weapons are only for personal defense). To balance this out smgs and shotguns should only be available to them. This wouldn't only create some fresh gameplay but it would balance the game more. People would be forced to play more as a team. You wouldn't be able to rambo with the assault anymore and you would need some medics to succeed. This woudl solve the problem with assaults who don't want to play medics.
