It is much more difficult... I can't get the hang of battlefield. But whatever floats your boat.

Battlefield and CQB are very different. A team oriented game vs a laser lined shooter caters to COD fanbois. If you've played Battlefield, you would get rekt. You adapt to a whole new level of skill sets. Not aim and fire, you have much different scenarios. You have borderline reality with muzzle climb, stability, hip fire, different types of barrels, different strengths and weaknesses. There's no 10 story building jumps, there's no sticky grenades, there's also no real radar unless you're firing your weapons. Hit boxes are different, weapon weight, your speed, everything is different. The easy button is so great in Destiny it was just a wash.
