dogs are just pissy whiners. they take 1-2 bullets to kill, spawn in the same places and go to the NEAREST player.
helicopters are bitches. their #1 priority is to hunt the #1 enemy player, and instead of taking random movements and shooting at #2 until he gets a LOS at #1, it'll hunt him with a UAV. which means they hunt me constantly :\
most of the better players play COD4 because of the spawning.
before i sold W@W, my primary account was 18819 kills, 1.64 kdr, secound account was 5045 kills, 3.22 kdr. it was over 4:1 before i gave it to my buddy to play.
