After over 1.5k hours played, I've seen a lot of improvements. For the most part all are well received. Here are few items I feel are worth considering based on my experience and those around me. These recommendations are primarily for official gameplay.

1) All vehicles should be able to maneuver up hill terrain, major torque adjustments required for large vehicles.

2) Trailers for the supply trucks and/or towable equipment like portable radio extenders, supply trailers that can be pulled by construction trucks, fuel trailers pulled by repair trucks, etc.

3) More value to ranking, in most games several player reach top rank, there is barely any benefit to gaining Captain and Major. A shift should be considered, at the beginning of a match, team leaders should be able to place items for construction but Privates shouldn't have much ability to do anything. Corporal can unlock everything currently available for Private and shift all things back 1 rank. Attack choppers should be for captains. BTR for Lt. and BDRM for Cpt. Other similar changes at your discretion but the point is make it worth ranking up, slow down the overall progression.

4) Heavy armor vehicles need better resistance to rpgs and armor piercing rounds. not proof, but resistant. One rocket shouldn't destroy a tank.

5) An option for a ground troops to breech a vehicle and drop a grenade, this can be class specific or require equipment but should exist.

6) Engineers should have an increased experience gain on base building, on a per unit basis, not the assigned objectives, that experience is sufficient. this should be applied to all classes, transport gets bonus for troop and supplies transport, recon bonuses during overwatch, increased kill experience for attack classes. Encourage the classes to do their jobs more.

7) To extend on class specifics, vehicle spawning: Medics can only spawn ambulances, transport and engineers can spawn supply and transport trucks, etc.

8) Only team leads should be able to spawn ai at the living quarters.

These are the most notable and most commonly discussed issues, If any or all are implemented, the quality of gameplay would be greatly increased.
