There is no "lone wolf mode" in BF3. I think you should take a break from trolling the forums.
Unless you are talking about not joining a squad, then you are a "lone wolf"...
UH Recheck the Battlefield field bog on play it your way and squads.
I just found that blog. Its not a "Lone-Wolf Mode" as such. The blog says that DICE have twecked the gameplay & Class's to make the game abit more friendly for lone-wolfs. Each class will be a little more balanced then we have seen before.
