This is coordinated teamwork at its finest. OP was right it looks unfair because the other team had no way to challenge their tactics. If Deej really is looking into it, Id say a fix should be nothing more extreme than having orbs in PVP despawn after a countdown. This was absolutely the way the game was intended to be played all the mechanics were put to their most efficient uses. I would hope this isn't the first time any bungie testers have seen this because we'd have a lot more problems.
