If I had more willing friends, I would be playing games like Capture the Flag that require a lot of team work. But usually we play slayer and "soft" team games like king of the hill and oddball where it is possible to win without heavy communication.
I guess you could call this post a cry for capture the flag players...
Isaac, it'd be a nice change to complete the team based challenges without all the lone wolves out there. I added you as a friend from the 'older gamers' thread but have yet to play a team gametype with anyone with a mic.
My go to playlist would have to be Big Team Infinity Slayer although I regularly mix things up. I agree with you on the SWAT. It feels really off most of the time when playing in Halo 4. It's something about the pacing.
