Eh getting perks can be tricky.
Plus I play with randoms mostly. (probably my biggest problem)
Anyway I also dislike the weapon loadouts past Blops 1. Too many modern/futuristic weapons. One of the reasons I'm looking forward to COD WW2.
I still have to disagree with that. Getting power + perks always stayed easy.
(Except for Shadows/Zetsubo which weirdly has a harder time turning on the power than any map.)
