The main argument I hear about it is that it's a less-ranged MP7. That's complete bullcrap. There's WAY less recoil on the vector, and it's completely vertical so it's easily managed. You can kill people from so far away with this thing, further than any SMG; in fact, I consistently beat out peacekeepers on anything except extreme across-the-map scenarios. The only major downside is it's range, but that can be remedied with long barrel. I have to admit without the long barrel (or god forbid, you put the silencer on it) it's range is just abysmal, but with it I've noticed a huge improvement in its performance. Given how fast it fires and its little recoil, the vector is also the best SMG to strafe with, even with stock it's still easy to stay completely on target. I've just had way more success with this than any other smg. Even if people still think it's the 'worst' smg on paper, it's still head to shoulders above the rest weapon class in this game anyway. This hate is unwarranted.
