Some scorestreaks can not be choose when an other with the same lvl of power has been chosed.
Perk Slot 1: (Blue)
Perk Slot 2: (Red)
Perk Slot 3: (Green)
I think it's just speculation or some kind of wish list. This basically just combines the features of the past games and their rumors (such as the extra tiers of pro perks which were supposedly going to happen in Black Ops 2)
The reason I ask is that this list has come up several times over the years. I'm wondering if it's the same false "leaks" that we've been seeing
It doesn't even have the new gamemodes (Blitz, Cranked, Search and Rescue), and there are no more perk slots. WTF....?
