escaping encounters like blockades, piracy, maniacs, in open by going to another game mode is an option that FD poorly chose to allow to exist. So long as it exists, you wont ever have a really effective player driven event in the game that consists of opposing players.
It's not that open play NEEDS players to be kept in open even if they dont want to deal with scary human players. It's that open play NEEDS the players in the other modes to not have any impact on what goes on in open play. Only then can you have an effective player driven / determined event.
Sorry, but every event so far HAS been player driven and determined. Unless it's being played by programs, that is. Mode does not determine player participation. PLAYERS determine participation. Personally? You'll NEVER have to worry about seeing me in open. Why? The attitude displayed by posts much like this one, which boils down to "play our way or go play another game". I spent just as much to purchase the game as anyone else, therefore I have as much "right" as anyone else to play the game. Oh, and to play it how it was advertised. I suggest that punishing the reaction to blockades, piracy, maniacs, etc. (hopping to solo) is lunacy.
Punish/eradicate the cause, not the reaction. Then you'll stop getting the reaction.
