I respectfully disagree, SP and Jugg were perks that outweighed the rest of the perk slot choices. They each basically force you to use the other to counter the extra bullet damage/resistance. But as we learned with BO, without SP and Jugg there is still perks considered overpowered (Ghost).

The worst decision IMO was to have SP in MW2 and not Jugg.

BO and MW3, in my opinion, will be known for having the most "fairly balanced" perk choices to date. So much class customization to be had in both games, moreso in MW3 it seems with these proficiencies
