I've noticed during double exp that the most played class is an engineer. Most likely because of their ability to drop the ammo pack, then head over to repair things. The exp on average from this is about 150exp for a turret repair, and 30exp per resupply. (based off a night on the crown). I've already certed quite heavily into the engineer prior to this, along with the combat medic. But I find more exp and certs are gained by running as an engineer. As a result the other support class is lacking. Perhaps to entice players towards combat medic, a dropped med pack could be introduced. A slower rate of heal in comparison to the medigun, but a heal none the less with the same tick ratio as the ammo pack.
