I'm actually quite spray happy to, I mean I have ammo boxes, why the hell not. What you really want to be looking at is how many kills I'm racking up in how much time. You've played 46 more hours yet I have 500 more kills (without meaning to brag of course). From what I can see your stats are perfectly respectable. I do quite clearly play Assault most, thats the job I've assigned myself for my normal squads because it's what I do best get to the objective, kill anyone who gets in my way and then make sure nobody gets near it again, or try to.
What I personally have always been a master of is movement, quick, decisive and precise, I know where I wanna be, how I'm going to get there and what I should be worrying about, and then I probably plan out in it's entirety exactly how I'm going to get something done after that, and after that, and at the same time the second something changes in the field, I already know what I'll be doing instead, and where I'll go from there. It takes me a short amount of time to memorise a location, photographic memory, so I also know exactly what I'll be doing on the other side, and how I'd counter myself in order to succeed. So I know what I'm doing, what the enemy is very likely to be doing, what I need to do or not do subsequently, so then I know what I'll do instead, whilst all the time remaining a few steps further ahead. Factor in decent eyesight and I'm good to go, if I sat at a friends house, much to their annoyance or sometimes they're glad of it, I'll be pointing out enemies on their own screen long before they're aware of it.
Everything about the way I play any game, driving or shooter, is all about keeping everything active, eyes, ears, even my fingers (I always double swap my weapons on games like COD to keep myself at peak awareness, and on driving games I'm looking behind me every few seconds even on turns). People think I'm very twitchy when I play, if I'm by a window, I'll look out of it for half a second, and move back and repeat and then people ask what the hell I'm doing. That split second is all I need to spot a movement for the most part, and then I'm not sat with my head hanging out.
It's difficult to explain, half the time I'm so far ahead of myself even I'm not sure what I'm doing, but I just do it. I can just take in alot of information and process it very fast if I'm involved in doing something, I can't read books or watch TV unless it's very specific to my tastes because I'm not involved. Most people have to spend a long time in a game to be good at it, most of the time I can do well from day 1 even with a terrible aim because I can still get inside peoples head, and it takes me a lap of a map to get an idea for where the important thing is.
