I honestly disagree; you choose a primary, secondary, perks and a throwable. The formula is used on pretty much all other modern FPS, if not similar.
Before bashing on a game, maybe you should learn the first loving thing about it beforehand.
The "Pick 10" system changed everything up. You get 10 points to use on primaries, secondaries, grenades, perks, etc. You also get wildcards to give yourself a gun with 3 attachments or 2 primaries or extra perks/grenades. You can create a secondary-only class, a grenade only class, even a knife only class along with the default stuff.
Also the nerfed knifing and explosives are things to note.
