I hope people do not get the wrong view about the LE, it does not cost extra so if you have the chance to buy it you may as well, it gives you access to a couple of weapons and perks for use in multiplayer which would otherwise take you a while to get from ranking up
The idea behind it as I believed, is to have a fixed amount of copies of the LE mainly to be giving out during the launch period after this period has gone, it will return to normal copies, this is to give potential customers more incentive to purchase it on or shortly after release instead of waiting for price drops or pre-owned copies where EA/DICE will make less or no money at all
