Yes exactly, why have them in the first place? If its purely cosmetic like it is in BC2 after level 25 then it doesn't matter, if people want that sense of 'achievement' then let them (though in BC2s case it was more a sense of epeen to be on the leaderboard). The unlock system on BC2 was utterly ****ing stupid, "Excellent you've chosen to start off as a Medic... oh wait we didn't give you a Defib or a Medkit..." or "Excellent you've chosen to play Engineer... here you go have some useless SMGs that are absolutely dreadful in comparison to the later unlocks that everyone is killing you with". With MW it didn't matter that much. You had enough unlocks at lvl1 and most of the later guns weren't better, they had pros and cons like they should do but its still frustrating for new players.
