I used to beast with the Galil. K/D was over 2.00 with it for a good while, then it slowly dropped down to around 1.5 for no understandable reason. In the meantime though, my W/L is well over 1.10. I'm happy about that more than anything else.
I play pretty much Domination only, with a bit of S&D. Other than that + a few games of FFA/TDM, I don't play with the other game modes. I like One in the Chamber but I don't really need money anymore so I don't bother. I'm also on 4th prestige with pretty much every emblem/background that I can get.
Also, I dislike the FAMAS. I don't understand why people like it so much, honestly. I think the Galil is much, much better. I'd even say it's the best gun in the whole game. Or at least the best assault rifle.
and clearly rpgs are the best weapons ever
Edit: Also, whoever uses RC-XDs should go kill themselves (not really, but something bad). Not only do they seem to have a heat-seeking system in which I am always the target, they are completely and utterly outclassed by...the Spy Plane. Seriously, you'd rather get 1 or 2 kills than help the entire team out for a good minute? Plus, you could probably get at least one more Spy Plane just by having one up. It's a killstreak that keeps on giving and giving. I seriously think the RC-XD is the stupidest thing to ever cross a CoD game. Oh, and Valkyrie Rockets are pretty stupid as well. Impossible to control in tight spaces and also pretty helpless compared to the Blackbird, which I believe only requires 1 more kill.
That said, I have Spy Plane/Blackbird/Attack Dogs as my killstreaks. Sucks that dogs require 4 more kills than they did from World at War, but that's okay. STILL WORTH IT
Edit 2: Oh, Second Chance. I don't even know what to say. Just take it out, and I'm sure everyone would be happy (except the people that use it, but obviously no one cares about them). Noob tubing seems to be less of an issue than it was in MW2, at least. And Ghost. Oh my God, if there's one thing I hate more than Second Chance, it's Ghost. Seriously. I don't know why more people aren't complaining about it. When there are 6 people on the enemy team but the Spy Plane only shows 3 or 4, you get a little paranoid about everything and it drives you insane. I. Hate. Ghost.
And I play on 5 sensitivity. Any higher and I have trouble longshotting opponents. Any lower is a little slow.
yeah i think that covers everything
