Time to unlock all of a class's weapons is insane.

I have about 40 hours in the game now, ~20-25 of it has been medic, running SMGs, revive masks and eventually defibs. I stick around team mates as much as possible, I'm constantly reviving, healing or stimming teammates now that I have the stim unlocked and I'm only level 15.

Unlocking the last smg happens at level 35 which requires 750,000 xp. Level 15 is 110,000 xp. At my current rate this means that it will take me about 140 hours on the low end, and the initial mag size is 13 (FOR AN SMG) until unlock the 30 round mag at level 38, which requires 875,500 xp.

This means that in total it will require right around 160 hours just grinding medic to unlock the final gun and have it be usable. This is an absolutely asinine amount of time for this unlock.
