By action, i mean everything, regardless if it is scavenging, PVE, PVP, questing, etc... Everything should have its share of risks. Of course, not all kind of action should bear the same risk. Some actions should be a bit safer, with lower reward, so new player get used to the game.
PVP is currently the most complete feature in AOP, but it doesn't mean it shouldn't endorse other usual aspects of FOnline MMOs. It is even necessary if they want to attract other kinds of players.
About TKing, it only happened within VTEC or very specific situations when player X is angry agains't player Y. Other than that, most new players were welcomed quite well in factions i've been part, especially when the overall number of player started to decrease.
About neutral players, i mean every player that don't shoot other players (of different factions) on sight, outside of ZC. With auto-capturing those situation were less frequent, but there was quite a bunch of players that wouldn't shoot you on sight, before it was implemented. I can name Count Matthew, Vault Boy or myself, for instance. (and many new players are also initially quite pacifist at first, considering they aren't good at PVP and don't want to risk their stuff) And even after auto-capture was implemented, we were spared by quite a lot of players when we were playing factionless. Neutrality is already a thing in AOP, even if it is not quite frequent. At the other end of the spectrum, there was also other players playing lone wolf, attacking other players (from other factions) on sight, even when they were alone, like Komrade, Hellmoi or Redrum. (i am not blaming those three. It is the risk when you wander in the wasteland. You can meet hostiles or friendly fellows. You never know)
