Have you ever noticed that everybody talks about how awesome they are at CoD4 online? I can't think of too many people who say "I'm average" or "I'm not too good".
I'll come right out and say it: I'm decent. I have matches where I kick butt and I have matches where I'm at the bottom of the list. It happens. I have a 1.10 kill/death ratio and you know what, I'm OK with that. I don't hate on people better than me and I don't bash those that I am better than. I have noticed that in playing clan matches with my clan, most guys in clans are decent enough, but you still get the occasional jerk. I'll see a team deathmatch where all the players on one side are in the same clan but 1 or 2 and if that team loses, the clan guys rip on the other guys like it's their fault they lost. Get over yourselves people. If you're so awesome, why couldn't you pull your team up? I've seen one guy take over an entire match several times before.
I understand there is a certain level of trash talk and that's fun and makes the games more interesting, but why do so many people think they're such hot stuff? I know I'm usually getting more kill than deaths, so that means there are more people that aren't as good as I am than there are people who are better than me. Can't tell on the message boards though.
This board is actually pretty good, but some of the other major boards are a joke. Everybody complains about snipers, noobs, grenade launchers, juggernaut and so on. Why? This game has EXTREMELY balanced weapons and perks. You give up some things to gain an advantage on others.
Sorry for the rant, but it's all the jerks that make XBox Live such a joke sometimes. Everybody (mostly anyway) is there to have a good time, just get over yourself and remember, it's just a game. It's pretty pathetic to rip on less experienced players, being good at a game means nothing in the real world. But maybe that's the problem, it's probably all the people with absolutely no lives that feel the need to do this.
