Seems like just unlocking mechs and doing all of their training missions is a good (if kinda boring) way to keep leveling up. It also has the benefit of learning everyone's kit, which is going to make you better at the game, since you'll always know what you're up against.

I agree though, I'm not crazy about them locking solo queue for the PvPvE mode to level 13, since it's what drew me to the game in the first place.
