Here is a Joystiq article from a guy who's played the (almost) final build.
He goes on to describe the change to the feel of the game... well worth a read. Looks like high damage bullets are out..
It appears he is wrong. Someone on Ars summarized some DICE tweets on this issue here.
There are posts to twitter from alan kertz from today where he goes in depth on the damage model. Their baseline for damage was the xm8 with the magnum perk, and that despite what the joystick guy thought, other than some minor tweaking of indivdual weapons the damage model hadn't changed since the beta version. Higher caliber weapons like the m60, scarh, g3 will take 3-4 hits to the chest depending on range, light caliber weapons like the 249 and various ars will take 5-6, which is pretty much spot on with what I was seeing in beta, bar abnormalities like the various pdws. There are also several more articles and youtube videos around from people that have played that same version that is used in the joystick article that contradict what he is saying.
I thought the Beta was fine. If they do any more bullet sponges they might as well call it Halofield or Gears of Battlefield.
Oy, I have been following threads online about this issue. Everything from guys wanting health doubled to SL getting more health because they are "useless" and cannot enter the battle The worst part is the arguments AGAINST flanking. Yeah the only skill worth rewarding is holding the crosshair on a target, never mind the art of surprise.
