I got another question. I've noticed, as I get unlocks with rank, I can only get the first level unlock, but never the second. I play medic a lot and I'd really like to get the next medic gun unlock but it wont let me. On the other hand, I see tonnes of people at my rank who have unlocked both sets of guns for a few classes. What the hell is going on? Am I missing some kinda button that says next weapons or what?
