Used to be all out combat.
You are aging faster than you should, young Jedi.
The game hasn't been all out combat since at least late 2001. There have always been runners, gangers, hordes, NOE missions, HQ porkers, vulchers, and utility griefers. I believe there may be a lower proportion of dogfighting afficionados now, probably because many of the original crowd who longed to fulfill their childhood dreams of being WWII fighter pilots has died, drifted away or lost their minds. But if we had films from 2002, they would show about the same dynamic as we have now - with almost the same number of people.
So pop a beer, find a comfy chair that has a footrest, and listen to "They Way We Were" while you gaze out the window and vegetate.
