To me, AvA in Cyrodiil is more stressful than PvP in Cyrodiil and the Imperial City.

I'm not talking about just doing scouting missions and capturing resources, because those are essentially one-off missions, by which I mean you do the mission, turn it in, grab another mission, do it, turn it in, etc. And if you get killed before you complete the mission, you can either keep going back until you do complete the mission, or just put it aside and come back to it later when the map has changed.

On the other hand, if you try to get into AvA, you need to coordinate with your fellow alliance members-- assuming there are any in Cyrodiil in whatever campaign you're playing, and that whoever's in Cyrodiil is actually interested in doing AvA as opposed to just questing or doing one-off missions. And the stakes are more urgent. If one of the other alliances is trying to capture your scrolls, or has succeeded in capturing a scroll and is running it across Cyrodiil, you don't get another chance at a do-over if you get killed, the way you basically do if you get killed before completing a scouting mission or a mission to capture a resource. That means you care more about the outcome of each fight, and consequently it's easier to get upset at your fellow alliance members-- for not being there when you need them, or being there but not being as effective as you think they should be (and yes, I've been "that guy" many, many, many times, so I'm not throwing stones at anyone else because I know there will be a lot more being thrown back at me; I'm just making an observation about how intense everyone's feelings can get). If you fail, it matters more than if you temporarily fail at a one-off mission, or at a city quest, etc.

I can't decide if I want to get more deeply into AvA, or just run as far away from it as I can and just stick to those one-off missions.
