I think BF3 works better if you are organized
Absolutely- that is the joy of BF3, teamwork and strategy. When something goes 'right', it is just an awesome feeling.
MW3 works better in lone wolf mode as your personal skill matters far more but god forbid you have an organized clan in the lobby and they halfway know what they're doing.. you have no chance.
True dat! Whenever I'm in a lobby and one side is all the same clan tag, I am out of there! But that does make the point that you CAN have coordinated group tactics in MW3 and using them DOES give you a significant advantage- it's not all 'lone-wolfing'.
As I say, they are both good games- although yeah, BF3 really feels less polished next to MW3.
