I'm on level 6 after 2.5 hours, but not bothering to level up quick, which I can by going gunho on Sabo (less fun without clan or grouped with others on friendlist), but I'm corious on aquisition and been playing it mainly, its weird and challenging mode, not a mode for levelling up too quickly. Especially without proper teamwork. But the mode I havent played before (besides supp, but its boring and easy), so doing it mainly.
