On the topic of sending people messages, I make a point of sending everybody who BS'es me with commando, and everybody who uses Akimbo Shotties.
Commando is a pain, I use it to get challenges, but I JUST got out of a game with someone using it, and my whole team is so stupid that they can't do anything about it. The whole enemy team is rushing, my team is camping, I don't want to be sitting in a corner so I'm getting boxed in and my team can't stop one person (a sniper) running around with Commando getting them in the back.
I'm fed up with this game to the point where I feel like taking off for about 3 weeks. What I'm sick of is the lack of good players in this game. All the people on my friends list is in their own groups, or so crappy that I don't want to play with them. And I can't go into game chat to make some new friends because every person that plays the game is some stuck up know it all who runs his mouth because he can camp or tube. They all think they're something because they have a 1.0 K/D, they're glitching 10th prestiges, they have their little buddies in there to help yell into the mic when they know they're wrong, and so on. So here I am left with a broken game, no good players to play with, and people who run their mouth like no tomorrow where I wish I could meet them IRL so I could break their face.
I send messages all the time. People who glitch on the maps, people who just go around and use tubes, people who camp, and so on. I send more messages then I should, but it's part of the game. And sadly, 99% of the time there's something in their mind that tells them they're always right. Camping is ok, only using tubes is ok, glitching and boosting is ok. These people you can't reason with them, because they're skill-less, and I call them lifeless. Because they have a great life if them and their buddy sits in the back on an S&D match that shield boosts.
After watching my brother play Uncharted 2, makes me want to throw the MW2 disc out and pick up that game. Because the players on MW2 just piss me off (I have never been so pissed at a game, and it's only been out for a little under 3 months).
