BO1 was not noob-friendly at all due to its design (maps, guns, killstreaks). You either got good or you continually went negative and/or ragequit.
BO2 by comparison very much holds your hand. The maps are designed to funnel people into chokepoints. They're very small and don't require much awareness. The killstreaks spoonfeed you kills. The guns have almost no recoil.
