The more people who realize that efficient kills are lucrative kills, the easier it will be to acclimate a group or even a PUG to this playstyle.
Right now, aiming for the legs is a completely alien concept for most players - especially MW4 vets who consider legging to be a dishonorable tactic. It's gotten to the point where min-max builds are starting to throw ammo into the legs and strip all the armor off them.
The sooner people wise up to this mechanic, the more they'll be able to reap from it. I have no qualms with sharing what works.
