The Black Ops 2 Create-A-Class has been completely revamped and updated. The multiplayer Create-A-Class features a new 10 point system, also referred to as "Pick 10", which gives you 10 allocation points to use on weapons, equipment and perks. This system is extended with the specialist classes in black ops 3 by giving you even more freedom.
Each weapon, weapon attachment, perk, and equipment uses 1 allocation point, but you can only spend 10 allocation points per class - you, of course, get to choose what you take on the battlefield. If you don't use perks, that saves you 3 points, which can then be used to equip more weapon attachments or grenades. You could also carry only a secondary weapon with 2 attachments, have 4 perks, and one grenade.
The choice is yours.
You can also optionally choose up to 3 Wildcards for your class, which in turn give various options to customize your class even further. For example, by default your primary weapon can be equipped with 2 attachments, but with Primary Gunfighter the weapon can be equipped with up to 3 attachments.
Each selected Wildcard uses 1 allocation point. All Wildcards work exactly the same way on the Xbox 360, PlayStation 3, Wii U and PC versions.
NOTE: Some Wildcards, like the perk greed, "require" you to select an additional perk, which also uses 1 extra point. If you want to have 6 perks, the first 3 perks require 3 points, after that each additional one requires 2 points (1 for the Wildcard + 1 for the perk), for a total of 9 allocation points - this of course leaves you only with 1 point to spend on a weapon. The Wildcards in Black Ops 3 are pretty much the same as in BO2; you can create similar setups with the wildcards in black ops 3 by making use of the Specialists system.
