"like the AK-47 in pretty much every game since MW2 (expect Black Ops)"

MW2 is the only game so far where it's unlocked at last level. In CoD4 it's unlocked at Level 4/55 (I know you said "since MW2", but it's worth mentioning), in BO at 38/50 and in MW3 at 68/70.

So that argument is kinda flawed.
