Couldn't have said it better myself Wacco.
I have my ups and downs, but when I'm on my A game, I decimate almost everything in my path. I think to this day my best record is 46-3 on Panama Canal, while that's not as impressive as some of you who go like 60 or 100 something, I'd like to think that since I was running solo with randoms, that's pretty good.
Regardless, it's something that's innate I think, something that you just pick up the more and more you play. Talent perhaps? The ability to look into a situation on the fly and be able to process it right then and there?
If you really look at it, a really good player kind of plays like a Chess player, always trying to think four or five moves ahead, and predicting the way the fight will progress. That same thinking kind of applies to games like this. Sure you can be great at aiming or pulling those no scopes off, but without that ability to adapt and react on the fly, that seems to be what really limits players.
Not to say you don't have those qualities Texas, it's most likely you've just not unlocked them fully yet. Time and practice I suppose are the best advice I can give you.
Another example, when approaching C on Panama Canal from the boat between C and A, people usually hide in three places, either in the crates, in the corner closest to the outside stair cases, or the small door on the opposite side. All three of these locations offer the best means to cover the various entrances, thus, you approach the door way at an angle so that you have a view of the stair case inside that leads up to the second floor, secondly you check the corner directly left of the door, and finally you make a quick sweep of the crates and then the far corner where they usually sit while capturing the flag.
At flag Alpha, four places they'll hide, either behind the dumpster below the tin shed thing, behind the destroyed car under the same shed thing, in the corner where another destroyed car is by the flag, or within the building next to the flag. Knowing these locations and committing them to memory helps in predicting what the enemy players will do.
Throwing a grenade will more often than not make the enemy run a specific direction. Use that to your advantage in locations like B where they like to hide behind the crate. Throw it to the left corner, and they'll most likely run right, or throw a grenade behind the crates and quickly shoot them, they will most likely run behind it for cover, only to be taken out by the grenade.
You have to do this stuff on the fly, you can't really think about it, it has to be something you do automatically, it must be committed to muscle memory if you will.
There's more I could add, but I think you see my point. And no offense to you if I came off as being a prick or something, or if I accidentally insulted anyones intelligence. I have a bad habit of getting into these "lecture" or teaching type modes I suppose. So my bad if I irked anyone >.>
