PvP on Cyrodiil rocks!!
You enter Cyrodiil map, then find a group or make one and then lets the siege begins, doesn't matters If you aren't veteran rank, because the sieges will do the job for you, doing a lot of damage to every enemy player, you can kill veteran rank foes just aiming well
I have had so good times playing pvp, is really fun, a lot of people, like 30 or more sometimes, running by keep to keep annihilating every other faction sign in a few minutes
Also leading is really cool, you say "people go to there" and everyone supports you
But in pvp you have to stay with the group to survive, a really cool "social" experience, working in groups
In pvp you are living the tales mentioned in lore books of Elder Scrolls
So take your sieges on and lets raid and raze every point until take the whole map, to not let play anyone other faction more xP
