Promotion Upgrades?
I think the entire system of promotion should be more than just unlocking weapons. Players should be allowed to change their characteristics around..
ie.
You can add a level of armor to one class
Be able to carry around more ammo
Have your heal/fix packs work better.
Increase sprint distance.
These are just a few things, and I believe could have been pretty easily implemented into the game. For one, every player would be unique, and it would be more worth going farther in rank if your abilities could get better.
