So why haven't you looked through the Dangerous Groups Subforum yet?
I rarely run into anyone else in Open unless I'm participating in the Community Goals or otherwise heavily populated systems.
It sounds more like you're letting your fear control you rather then accepting open for what it is then based on any actual experience of being ganked. And I've been exclusively playing open since 1.2.
I'm less inclined to care about what you have to say as well when you've been playing Mobius exclusively since 1.2 meaning you have no experience that Open is a gankfest.
If your daughter wants to play with others then scroll through the Dangerous Groups and talk to people in them. Plenty to choose from and I wouldn't be surprised if they had their own private group channels to play on when they organize something big they don't want disrupted.
Also hate to tell you this but your belief that the weapon's update is PvP centric is misguided. Weapon's upgrades help those of us who PvE as well. I've run combined arms and I'm more then excited to see what changes to fixed will do in helping me kill bigger badder NPCs.
Anyone can snipe a powerplant with fixed weapons. I do it all the time fighting CZ Anacondas in a Viper 3 as of late and I'm no PvP god.
Besides you clearly haven't been paying attention. The Beta was a test. Fixed are getting buffed. Gimbled are not getting the nerf. And Turrets were never being touched at all so I have no idea why the hell you brought them up. Sounds like you need to pay more attention to the news and announcements as well.
This is actually hilarious and proves that you only read certain posts. A player proved that players in open will even gank inside the damned stations. There are so many posts about people being ganked and you will find that many of the prominent youtubers do not play in open unless they are PvP players.
