The fact that there is an instancing system whereby players can meet other players, and can be identified as such (via the hollow square) is much more than 'it can happen'.
Frontier could easily have only allowed collabarative mechanics such as multi-crew while not allowing you to instance with other players in separate ships. Maybe they live in a different reality bubble where nobody shoots at anybody else, but I seriously doubt it.
I think you misunderstand what I meant when i'm talking about "designed".
To give an example, the disparity in combat ability between small ships and big ships that was compounded when they added multiple modules that increased toughness as well as engineering.
I don't think anyone sat down and "designed" them from the point of view of PvP combat. Nobody said, ok, what happens if guy A in this Corvette meets guy B in this Cobra. Is there any sort of balance here?
My personal feeling is that bigger ships should actuallty struggle killing smaller ships more than they do (especially Corvette with its ridiculously high agility for its size).
Likewise with combat ship with trade ships. Of course i don't expect trade ships to beat combat ships in general. But how combat ships and wipe a trade ship configured for trade in a matter is seconds is a major PvP imbalance from my point of view.
Yes yes, someone will now post Rinzler's video. Very good, we've all seen it.
I think trade ships, knowing they will be going out into the black and facing potential pirates should be a lot tougher than they are by default.
Now, you might disagree with my individual points here as to what would make PvP better designed, but i hope you agree that it seems like FD didn't actually put any design thought into combat in relation to PvP, especially when they added engineers and all the extra modules.
