Any auto-leveling techniques or FAST leveling/farming to Level 20? Lost my save.

My hard drive was corrupted and I lost my save, now the DLC is coming and there's a damn trophy/achievement for getting to LEVEL 24.

Is there any stress-free ways to get to 20? I really don't want to do that again...

Be a medic. Buffing and using abilities give the most exp, and you'll more chances to revive teammates than to use other skills, like a turret or caltrops. You'll get around 7,000-8,000 exp a match if you focus on reviving more than attacking.
