How long did that take? You would literally have to scour every inch of each area to be sure... Aside from that, I disagree. None of the weapons have learning curves, the game has the most aim assist I have ever seen, and outside of PvP there is no skillset to using each gun. Besides, PvE counts as much as PvP towards those kills, so there is no differentiation there either.. I'm not going to think someone is better at the game than someone else because they have 2500 MG kills.
