Im curious to know what people say because im usually the one running around with my MP9-Silenced lol

The person who says "Really? You're running round with a secondary?" Because they died lol.

In seriousness though, I run around with secondaries quite early in the game, particularly the FMG9 and MP9 - not to be a little noob whore, but it's a fast easy way of ranking up. You need what, 100 or so kills to get your gun rank to level 10 which gives you 10000xp for hitting max weapon level, plus the red dot sight, akimbo and silence challenges also adding 1000xp per challenge won,

run specialist from level 20 so on your second fourth and sixth kills you get an extra 200xp per kill for achieving the point streak, etc etc you guys know all this already

What I will suggest though, is as soon as you unlock steady aim, make it your 2 point streak rather than an actual perk in your class - you get a tiny bit more xp that way, then, when you unlock hardline, make that your 2 point streak, with steady aim as your 4 point streak and scavenger as your 6 point streak, and so on... very handy and you rank up so many challenges on your way you'll be levelling up in no time

Most likely capitalising on Lag Comp. I mean an MP9 beating a UMP rapid-fire in a face-to-face is a no-no. But this game is so broken so who cares.

well if ur running around with akimbo MPs your a *****. Anything else is w.e who cares

For me I usally reply back with a "well you didn't expect me to use my shotgun on somebody more than 100ft away now do you?" then they put me on mute 8/10 of the time.
