In a different thread I posted this thought and maybe it's something to consider as a solution if we cannot have Dedicated Servers and in particular my preference Rentable Ranked Dedicated Servers as follows:
Simple allow Private Matches to gain at minimum XP and better all of the other Patches, CAMO's, Calling Cards, etc.
Yep some will boost but doesn't that get old after a while shooting your pal in the face in a corner?! Most importantly it allows legit players to play in peace and rid themselves of the hackers and IW doesn't need to lift a finger in the process.
What are your thoughts??
