I know the second i get online on blops there will be people that have unlocked everything and start pwning me with their overpowered guns. It will be worse than mwm because the kills needed to unlock a gun are from one previous gun and not so straightfoward like mwm so it will be annoying. good thing i can get a head start unlocking in this clan since im starting friday.
also there are going to be gun restrictions like "no snipers" or "no explosives" so that will also get annoying when playing WW since "noobs" will go for "no knifes" or "no snipers" or "no explosives"
