Being shot at by other players certainly affects their game - and that's something that, thankfully, the game design renders completely optional.
.... their existence in game is not simply to serve as targets for the PvP inclined - they have a choice in the matter, after all....
I stated the perfect balance makes them not anyone wants to shoot at.
And if so, it cripples their game harshly.
Unimaginable? [noob]
LOL! Wouldn't be the first time!
Would make me question myself.
How can it increase interactions?
There is an instance limit, which the both the main PGs have more than enough members to hit hundreds of times over.
Open won't increase the number of people in an instance, just change who they see in it.
Less systems to roam alone within high traffic areas.
The instance limit is most likely only exceeded at very crowded areas.
But most places are not crowded.
