I also hated this a lot, two players per screen on team slayer? wtf? Four players per screen on multi-team? Why? I would also like to hear the answer to this. --- "using the rhetoric of trolls is not the way, and it doesn't persuade me."
Let me explain this to you so you can understand. You and your friend have 2 xboxs you each have 4 controllers right. Now you want to boost in griffball griffball takes 8 players right so there you go you two fill up the entire game. Now bungie got smart and says you can't do this because they limit me and my friend to only be able to have two players on one xbox in the game. So now if I want to boost instead of just me and my friend i need at least 3 more people to make 4 all together making it harder to boost.
