Nah, just disable the ability to shoot and ram other players, and all those mode-switching complaints will dissapper...
Actually, a lot of this would go away immediately if there was a simple ability to flag oneself on/off for PvP- make the game completely open, allow for people who want to participate in space pewpew against others voluntary with a simple flag- and all of these divisive, polarized threads would disappear into nothingness.
I fear, however, neither "side" is going to get what they want- and this will continue until concessions are made that are satisfactory (not necessarily completely, but at least baseline) to both groups.
