I dunno, part of what made firefighting in odst so much fun was that you had to get a team together, if you wanted to get endure/deja vu, youd have to get a squad together and kind of get to know them, their strengths and weaknesses, what people specialized in and what they needed help with, it wasnt like on reach where you just join up with randoms and hope you have good teammates, it was a lot more personal and made ff more intense, for me anyway.
