One thing I haven't seen addressed is, do you gain experience for participating in PvP? I know there are quest you can do while you PvP (kill 10 AD players), but do you get experience for kills or capturing PvP objectives? Would it be feasible to level from 10-50 just by PvPing?

Don't forget Cyrodil also has PVE quests......which will become PVP if you want it, or if you are not careful.

But I am unsure about XP in PVP. I could swear I read it somewhere that you can level in PVP, but I can't be 100%.

Yes you do but it's a very small amount.

I might be in the way way way minority on this one.... However I hope there is an option to turn off XP gains for Player Kills *Any thing that is not a quest*.

I would like to not out level my Zone for my PVE quests....

I would like to PVE/PVP with my friends while they are online, and then PVP while they are offline. This would insure I don't get too far ahead of quests and be out of sync with them.

*Added note: I don't believe it would be fun to be 5+ levels higher then the PVE content....
