I am a casual player and a peaceful scrub. Yet, stats and quality grinding would be way more meaningful for me, if I could go out and test them against another equally inexperienced peaceful scrub. Not the "superheroes" that I stand no chance against. I don't mind staking my gear and something like 10% of my stats - that I could recover in a few weeks of playing, but not in a few months.
And because all other peaceful scrubs think the same, pvp here is mainly an end-game content for no-lifers. This is my impression - will be happy if somebody proves me wrong.
Update: PvP for me is being that guy in sprucecap in Ozzy's glorious video, except for I won't last that long.
