Played for a good few hours last night and brought my online time up to 8hrs 14mins and I'm really enjoying it.
Getting back into the flow of things on a map, Caspian Border, I really love and am finding my way around on more. My K/D is up to .96 (woo!), so I am improving. My system struggles with 64 players on a map when there's too much action going on in a small area and that totally feels like network lag. I've got to reduce my graphics settings or avoid 64 player maps if I want a smooth frame rate.
I try and ignore the K/D scoring and just get stuck in. You can make a lot of points just capturing flags and whatnot. It'll always irk somewhat when you see players with that kind of K/D ratio (45:3 etc) as you won't be able to fully account for how they achieved that and the creeping suspicion they were aided in some way makes you resentful when in fact there are so many unlocks like IR scopes, improved flack and the like which make soldiers far more invincible compared to the new recruits, that they are in fact not cheating so much as 'exploiting' the game mechanics.
That's always the thing with some skilled players - they seem to home in on the exploit, finding a good place to camp and perhaps with the help of a buddy, they spam a particular area with rockets and gunfire etc as they'll be able to rack up the kills easy. All the while others will be playing with a mind to breaking through those mountainous tunnels and trying to capture a strategic position for the team, desperately dying all the time. I personally feel there is quite an interesting psychology to online games like BF3, that people are divided into distinct 'types': your selfish exploiter and your self sacrificer being the more extreme ends of that scale.
Anyway, must dash. I have a tank to catch.
