Single player is purely single player no option of adding in a friend.
You can still add in a friend (or anyone) even if you choose singleplayer.
I explained how I thought it might harm the game experience for new players already (see posts further above). Can you explain how/why you believe removing a redundant button press that doesn't actually do anything would harm the game experience?
Edit: See, the fact that you yourself (and others in this thread) seem confused (and have been completely wrong) about what these two options actually do is more than enough reason to justify removing them. Those choices have given you the impression that there is some sort of difference between singleplayer and multiplayer modes, when there actually isn't one.
If you folks can't get it straight after all this time as an alpha/beta testers, how is a new player expected to not be confused?
