I have played these games for years and the amount of hours played should lead to far above average play. I have adjusted and tried everything to improve. I have watched guys on my FL's gameplay via theater and youtube and it sticks out how easy they make it look. I used to watch Gumps videos (bops and MW3) and they helped me quite a bit with his tips. I watched Whytie84's videos and learned a lot about moving around the map which helped me a ton and even suggested some of my favorite classes to him only to watch him get a MOAB the next week with said class. I watched DBLs vids and while I am a flag capping, tag grabbing whore I cannot even come remotely close to those scores even when I avoid the flag or tags like the plague.
I use kontrol freaks.
I use tactical layout
I went from a SD tv to a 55" plasma a month ago which made the game much better but did not help statistically.
I hard wire my connection and have my PS in DMZ
I try different set ups and classes that I see guys beasting with.
I move tactically, and rush at times.
I dont camp and I do camp when I need to.
I could continue the list for a long time but it all boils down to the fact that I have just over a 1 k/d no matter what I change or do. I had games in bops2 where everything went right and I owned everyone. I had a 76 kill game on KC, and an 82 kill game of KC. Yet I finished bops2 with a 1.14 k/d. Part of that is my own choices. I will die twice to take that sniper out before he kills 6 more of my teammates. I go negative in that instance but possibly helped my team + 5 or more if he is close to a high end streak.
I finally realized after watching my buddies 15 year old kid play the other day that I dont have the reflexes, accuracy, or sense of when to run away from a fight to stay alive. Instead I take everyone head on even if its 3 v 1. I miss those 2 extra shots when he landed them. He lands the first shot faster then I would. Either way I die he lives hence his 2.6 k/d and my 1.08.
Long post to get to my point here but I think most people feel like they are way better then they are, self included, which makes the game less enjoyable because you rarely live up to your own expectations. I get mad when I barely go positive but math cannot be argued and thats exactly who I am. If myself and many others would learn to embrace this the game would be much more enjoyable.
