Have you ever shot a real AK? They jump like crazy. Just watch any of the videos on the net of the freedom fighters in Iraq.
The first shot and maybe the second in a burst should be near your aimed target but there is more skill to it than a game can convey.
If you're on full auto you are basically in spray and pray mode? Without sufficient training to control the area of spread.
If you were complaining about the damage model I would probably jump on the band-wagon since I think the damage was a bit weak especially with the higher caliber weapons. Anyone hit by a .50 caliber Dragunov ( http://world.guns.ru/sniper/sn18-e.htm ) should be dead if not down to be dead shortly after being hit. Head shots unless a grazing blow would rarely leave the target alive let alone able to continue fighting back. Unlike the game.
I'm all for realism in games but it's my opinion they did a great job with Stalker as far as the weapons ballistics go. Wish the sounds were a bit more meatier but still they were good enough.
Still one of the best shooters I've played. Looking forward to this one buggy or not... I am down.
