Help needed for the "Trip Cap" Challenge!

So basically I need help to capture all three points (A, B, C) and hold them continuously for three whole minutes in Domination. I don't have a mic so bear with me however I do know what to do. I fairly good when I'm on a decent team. I'm on most of the day and this challenge has caused me so much anger. If anyone wants to help me, my gamertag is PerfectUniverse. Just hit me up with a friend request and hopefully we'll do it together.
