Yea because as we all know in MWF2 just a few bad players on your team can completely ruin the whole game for you... as they will bumble around and set off Killstreaks for your opponents, so you are subjected to Pavelows, Chopper Gunners, and AC130's against you all game long... while being forced to switch to your stinger kit and sooner, or later your team is spawn trapped.
Not so much in this game, obviously if most of your team is not going for the objectives. Like if say they make no effort to get in and set charges, or defend the MCOM stations sure you will lose, but if a few teammates are going on high deathstreaks, it doesn't directly hurt you.
I actually like not having to deal with Killstreaks in this game... sure you feel like less of a 'Bad ***' when you're tearing it up, but there's less of the type of people that just sit in one spot camping out because their Harriers are up and they have almost gotten a Chopper Gunner.... and in this game I find myself
always playing for the win.. where as in MWF2 if I was playing very well sometimes I would find myself just looking for kills alone... even if my team was losing at the objective.
