Unless I'm missing something, inviting people to your team is a bit of a tedious chore. Why do I have to go through 2 levels of menus just to invite someone? Why can't I just highlight them from my list on the right and click a single button to invite them to party? How shortsighted can you be Treyarch?
So I see you can open up the friends list with Y and hit the back button to invite. I am asking for a way to invite quickly from the main party screen when you see your friends on the right hand side. Also a way to join their party from that screen as well without having to drill down into their name.
