Yeah, I've been guessing there will be a future PVP war based on Deadra. Perhaps Deadric Alliances between the Princes, as we know Clavicus Vile is working with others. Don't think it will be in Cyrodiil, but rather a plane of Oblivion.
It's been done. Imperial City.
The problems of Cyrodiil don't stem from a lack of good ideas. The problem is that ZOS doesn't invest in Cyrodiil. I think the last thing most PVP players want is more PVE in Cyrodiil.
I wrote this idea in another thread and i thought i would share it here ....
So in the PVP you get to choose different Daedra classes all with their own ability ect starting at lv 0 and you have only basic first skills as you progress by killing other or doing other things you gain exp and skills gets unlocked.
Once when you reach lv 50 the cp points will be available the same to you.
Now the fun part....
Daedra players in Cyrodiil need to make sure all of the dark anchors are activated and kept active once when that is activated the Cloud Ruler Temple opens up and Titan Dragons come out ( with health of 40 mill or more) and take over the all castles in Cyrodiil ( imagine the view of zerging towards a castle just to see big ass titan standing on top of it) ...anyway all of the castles would be all black as they have been taken over ... in order to reclaim them you would need to close the dark anchors (once when closed the titans loose % of their health so the more alliances work together the easier the reclaim would be ) Or you can defeat the titan and move on closing the dark anchors once when the Titan Dragon is defeated you can claim the castle.
dark anchors would be defended by Daedra players ..spawning on the dark anchors will be available as the waves are completed.
Once when the Cloud Ruler Temple opens up and Titans are unleashed if one of the dark anchors is closed the Cloud Ruler Temple is closed if the dark anchors is then re open and re activates all of them again the Cloud Ruler Temple dose not open up again as there is a cool down.
Now that for me at least would be so SO much fun !!!!!
ZOS basically put Cyrodiil AvA on life support in 2014. It hasn't added significant new content aside from some captureable flags. Most hardcore players consider Cyrodiil to be unfinished and neglected. We want ZOS to give us reasons to utilize more of the map.
This isn't because no one at ZOS can figure out how to do this or because there hasn't been good suggestions. It is because ZOS has not invested development resources to Cyrodiil. Forget new content, it usually takes ZOS months to solve major bugs in Cyrodiil -- there have been some ongoing bugs such as loading screens, LOD texture/meshes, an FPS drop bug and others that have persisted for close to 2 years or longer.
So I think it's unrealistic to expect ZOS to release a brand new AvA map -- and everything that comes with that: quests, voice acting, itemization, etc -- for a gameplay mode it is already neglecting, its business model does not support and is plagued with performance and gameplay issues.
Though IC isn't exactly what you're requesting, it is AvA in the context of an epic war with Daedra.
I think there will probably be Daedric and Oblivion themed content for Battlegrounds, but I would not expect ZOS to invest heavily in new open world AvA content -- nor would I want them to before finishing Cyrodiil.
