I feel like the only thing they took from Black Ops I was the graphics (which I was able to overlook for superior game play).
The unlock features are really quite pointless as you can pretty much spend tokens as quickly as something is available which begs the question: Why have the tokens at all?
Ghost not being made available until almost the level cap... is flat out dumb.
Wild card slots give the illusion of more feature but the fact that the game limits you to a given number of perks/attachments/equipment makes it almost irrelevant.
I can't decide if I like the fact that killstreaks can continue to ramp up even after your final Killstreak reward has been used (meaning it cycles through again if you don't die). Cool for me... really crappy to be on the receiving end of it though.
Also I feel a bit bamboozeled it was marketted like it was really futuristic (not too distant) but still futuresque. It isn't and definitely not at low level.
Maps... I feel like the majority of the maps are garbage (carrier is the worst).
Thats about it for now... I feel like for ME and how I like to play I'm not going to make any use out of personalizing a class until I can get ghost and claymores.
1-55 using the premade Operative Class... LAME!
I had really hoped that the purchasing system from Black Ops I to purchase the loadout you wanted without having to wait for some arbitrarily designed tree was going to be back... instead they went the other direction with it and made it the worst design ever.
All in all... I wish I hadn't have traded in MW3, and I think I would like a refund for my purchase. I am NOT happy with it.
To those who are going to jump in to defend the game... save it. I have been playing CoD since the original. I am definitely a fan of the series, and say what you want about Treyarch VS Infinity Ward, but I think Black Ops I was the best. Ironic that Black Ops II is the worst imo. Go figure.
