PvP IS popular, isn't it? Just not with everyone. The game is NOT PvP-based, but accommodates it. I enjoy the fact that I can engage in PvP if I want to, be it indirectly through BGS manipulation and Powerplay participation (although admittedly, I haven't quite learned to like Powerplay just yet), or by actually meeting other player ships.
I had some interesting player encounters, especially during Alpha and early Beta when we did not have that big a playing field. Now I meet other players quite rarely, which I am happy about mostly, as I'm a bit of an introvert and will reluctantly engage in text chat but not ever in voice comms. The encounters have usually been interesting and fun, and I have only really encountered gankers in the beta tests - which is fine.
The pointless, inconsequential PvP that seems to be about just blowing others up for no real reason is something I'm against. Mainly because it just doesn't fit with a Pilot Federation that somehow manages to be independent of all other factions as well as strong and with clout. If the PF doesn't enforce some sort of internal coherence, it would fall apart and be absorbed by other powers.
