I asked this very question to the GOD of AOC development aka Gaute Godager:
have you developed AOC as a PVP centric game or PVE centric? Or perhaps have you tried to reach some kind of optimal balance between those two types of content?
Anwser:
We said we tried to do both. But I guess we didn't really believe the game could stand on its own without good PVE, and felt that not many PvP centric games made it big, back then - so PVE drove the development. It changes with time. I might have made it differently today.

So the fact is that PVE drove the development.
