Which class gives certs back the fastest? I'm kinda just gonna be playing support for a bit and going for kills when I have to. Both the Medical Applicator and Repair Tool are on Level 4. For Engineer I got a Utility Pouch, Tank Mines, and Sticky Grenades; they're really useful for taking out infantry if I'm getting camped. Usually I use the Tank Mines like C4 baiting MAXes and infantry around corners and stuff. For Medic I have the Shield Repair and Revive Grenades. It seems like I always play the wrong class when things get good. I'll go Engi because we're getting camped by 12 Sunderers, 15 Tanks, 4 Harassers, 2 Flashes, and a Thomas The Steam Engine Collectible bought off of Ebay for 19.99 plus shipping and handling, and then when I turn around to start places tank mines, all of them are destroyed and I'm surrounded by corpses that I could be farming for xp. But then when I play Medic nobody wants to be a Zergling so i can farm their deaths for revive ribbons. So which class gains certs the most. I get a lot of ribbons with the shield, but it seems boring.
