BO2 reminds me of a fast MW3. It's too chaotic but I understand because BO1 was so dull and slow imo.
The only good thing about this game than previous COD games is that one player can't dominate for a team to win. Everyone has to work together whether it is putting up UAV, destroying objects, etc.
I am still working on it with the shotgun but I will know if I like the game or not once I unlock all the perks and find a class I can dominate in. As of now, it's ok with a party.
