you can also go and try to take down enemy spawn camps and siegeweapons by yourself. i have been successfull many times.
You are missing the point of this thread entirely. OP did not ask for solo sabotage PvP, nor did he ask for PvE.
I would also like some small scale PvP objectives in Cyrodiil, but I think the main problem with trying to implement that would be making it so that a zerg of 30+ people cannot do it as effectively as a small group of 5-10 can so it.
