got my lvl 22 scientist to lvl 24 in the matter of 3 games. this 4x experience weekend is INSANE. I could go prime easily if I wanted too. (all of my classes are in the 21-25 range already)
Once I unlocked Prime Mode, I leveled Leader from 0 to 7 in one game, same with scout and Scientist 0 to 6 in one game. My highest personal xp for one match was somewhere around 23700.
I've raised all of my characters from 6 to 15 in about 5 hours with other things mixed in between that time. I want to try and get Prime by tomorrow evening. I'm only a couple of trophies away from Platnuming this game once and for all!
