Hi OP:
It's it's fun for you, that's all that matters, and carry on.
For me, on either Infinite Empire or The Bastion, SWTOR feels, well, empty.
What I enjoyed the most about WoW was that pretty much every day, I would have at least 5+ random interactions with other enemy players out in the world, which would end with one of us dead. (This was just moving around, questing, without me running around trying to force PvP on others)
With SWTOR, I've had a total of 4 of those so far, which is kind of a bummer, and feels pretty single player-ish to me.
From the start, even when populations were heavy, or full, I didn't see enemy players out and about.
If I had to guess they seriously overestimated server populations, and spread out faction quest hubs accordingly, especially at low levels. Consequently, I never see other enemy players.
Other than instances, I don't care so much about seeing other people of my OWN faction, but I'd like to see players of the opposite faction. (so I can kill them)
