I use either the M16A4 with a silencer and the Akimbo Rangers as the secondary. I use Marathon, Lightweight and either Ninja or Commando. I also use the M4 with grenade launcher and TMP. I vary randomly on different maps. Obviously sometimes sniping on Wasteland and Afghan.
1. Famas with Silencer and Full Metal Jacket...secondary rarely gets used but it's usually a machine pistol. Perks are Bling/Cold Blooded/Ninja (standard assault class)
2. RPD with Grip and Full Metal Jacket...secondary stinger. Perks are Bling/Cold Blooded/Steady Aim (anti-air class)
I usually switch back and forth between these two for the most part. I tweak them depending on the map. Haven't unlocked the M16 yet, but I have a feeling it will replace the FAMAS when I do in a few levels.
Favorite maps are Terminal/Highrise/Quarry. Afghan is growing on me as well as Invasion. I hate Overpass, Sub base and Rundown
I hate the three you do as well. I like Karachi alot for some reason, Skidrow is fun too, Rust is very interesting when you play there. I had an 18 kill streak at Rundown so I can't say much bad about it.
I'll add you to my Friends list in a minute, then maybe when we're both on we'll play together.
