I might not be playing in the same version of the game as you, but.... I've gotten one character to level 17, and haven't done any pvp. I did stick my head into Cyrodiil to look around when I hit level 10, but didn't do anything besides run around and mess with the catapults. Target practice. I then went back to Stone Falls.
Strange. I don't want to pvp. Too many of the people who have been pushing hard for it have admitted they want it so they can mess with other players, run gank squads, and generally do things that have nothing to do with the war in game.
While I do enjoy playing myself, I have found that a small group makes a huge difference in the pve. Its nice to have help. Instead of worrying that while I'm fighting npcs someone who just feels like killing something is going to shoot my character in the back.
Cyrodiil is there for people who do want it. I hope they enjoy it. I can't see myself going there for too many reasons however.
