Best Game Type to Level Up Fast
The best way to level up fast is to play Hardpoint. At the start go for a Burn Card that reduces the Titan Build Time. Capture the closest Hardpoint and stay there. Every 20 or so seconds you get 750 experience for holding the Hardpoint. You also receive extra experience when you take out enemy minions whilst holding a Hardpoint.
Once you get your Titan move onto a Hardpoint that can be captured with a Titan. Take and hold it and take out any enemy Pilots, Titans and Minions that you can. If you die or your Titan gets destroyed go to the nearest Hardpoint and hold it until you get another Titan.
The bonus per match is around 3000 to 4000 experience on top of any challenges and kills you get.
