Adding new infantry classes is getting o the point off diminishing returns. Which is not as bad as adding event or premium. Exclusive classes like rocket radio, paratroopers, and rocket artillery vehicles. Taking existing classes and introducing subclasses can add variety without breaking the game. Maybe even being able to pick subclasses on the fly depending on if you are the attacker or defender
Such as breaking the assaulters into skirmishers and grenadiers who would share the same base weapon smgs. Skirmishers would get six smgs but be limited to one grenade small backpacks and mags between 20 and thirty rounds. They would get more firepower but be limited by ammo to how long they can fight n supported. Grenadiers would have more nmo and grenades but limited to the old 4 soldiers with smgs. They might even get jungles clips or carbines to increase there versatility battle.
Riflemen could be broken into rookie and veteran squads with rookie squads bring larger 12 man squads but with fewer specialist class. Veterans might be smaller but come with either extended magazine or rifle grenades at a lower br but be limited to 6 man squads and no specialist. Machine gunner split between recon and defender finally splitting high capacity mgs and light machine guns into two roles. One would have more mobility able to climb short walls and sprint further and aim down sites more quickly
That would in time give three options the original balanced class with a heavy agile class and a heavy defence class. Just a few ideas I know this idea has been brought up before but here it is again. Move the current rider to being a light and add a heavy rider wheel open rider class. That is open top jeeps, light trucks and cars, no enclosed vehicles, turret or guns more then 20 or 30mm at any br. No riders with rockets unless there a anti infantry or b anti vehicle if it can kill both well or has more then three people it’s a tank. By open I mean I want to see from the chest up exposed or behind armor vulnerable to infantry weapons like rifles and machine guns, and hand grenade kills
