They all seem to be incredibly bad at decision making. I don't really understand how people make bad decisions over and over. For example, in my last game I got in the gauss hog turrent and some guys in a party wanted it, but I didnt get out. So they kept shooting at me and being lame until it blew up. And they didn't even bother to get it after the 2 minute respawn. What's the point of betraying someone if you aren't even gonna go to its spawn point to get it again?
Another example: just killed a guy who had rocket launcher, I'm with my team mate. I pick it up and as I'm reloading he charges over the hill to face 3 enemies and dies almost instantly. Why didn't he let ME go first? Is he blind or just retarded? It seems EVERY player I play with is just terrible. I never get in the gunner seat of a normal warthog because 99% of drivers suck.
I -blam!- wish so hard that Halo Reach had trueskill. about 50% of the time I get the most kills in a game (in btb) because my team is invariably retarded. I'd be a lot happier if I played with and against players on my skill level. I hate bad players who happen to be on my team. Not for their inability to aim, but because they're stupid.
Another example: theres 30 seconds left, we're ahead by 5 points. What's the easiest thing to do? Hide for 30 seconds, guaranteed win. Guess what everyone ALWAYS does? Carry on running about like a headless chicken. This means I have to rush out too to get kills to make up for the inevitable deaths. It's so dumb that it makes my head hurt. Why do people persist in poor decision making? You could increase your K/D by a factor of 2 if you make the right decisions.
