How about people just run dungeons or PotD? Bring food. Use FC actions. Make some friends or find Peter Paladin on your server and ask "Hey man, would you like to help me run [instance]?" The worst he'll say is no. The funniest thing he'll say is "Pay me".

Seriously, did anyone see that chart going around? PvE content still gives more than PvP. And loot. And gil. And materia. . . Like, no one was forced to PvP, and PvE STILL offers so much more. Where's the downside here?
