Well, I did not expect battles with thousands of ships as elsewhere.
Actually I wasn't aware the is a 32 Player limit to a system/instance. However I think 10 ships in front of a station you are docked in are enough to lay siege on it and sort out the ships leaving the station.
And I think a common enemy is a strong motivation to cooperate, while being able to avoid punishment for bad behavior is not.
Frankly I possibly just do not like inconsistent worlds with lots of backdoors, even if backdoors are part of the plan.
You only think they are backdoors because you are looking at Elite Dangerous through PvP glasses. The game is not designed for massive PvP as Rob Maynard pointed out. The way you are looking at it, the game appears broken. If you keep that mindset, you are going to be disappointed in the long term.
Solution: Find another game that suits your chosen focus OR realise what Elite Dangerous really is and join in the fun with the rest of us. Anything else and you risk your health, methinks.
