Call of Duty: Black Ops 2 multiplayer delivers a brand new create-a-class and Score Streak system that is geared towards empowering players. Treyarch has told VG247 that it doesn't want you to play by its rules any more, saying that there is no need for rigid class systems any more.
You could build your soldier in MAG as well.
More games should do that.
A decent amount of people are still on it though, and you can still get games on every type of mode, but it just takes a little longer at some times of the day.
Maybe a good few years ago.. Now you're just playing catch-up, dudes.
That being said, I think this new "pick 10" system is a baaaaad idea. COD already had balance issues, and this new system is just gonna multiply those problems tenfold.
Treyarch did a great job at balancing Black Ops. Sure, it wasn't perfect (AK74u, Spas 12 supressed, Famas & Second Chance), but it was far better than what IW did with the balance in COD4, MW2 and MW3.
MW > MW2 > BO > MW3
MW2 has some fucked up perks but "Hit Detection" makes it superior to BO.
Well that's just like, your opinion, man.
