Hey there!
I am not the type to usually post on forums, however an idea occurred to me and it seemed quite worthy to share it with fellow PvP lovers.
So for the idea. Anyone that plays even PvP needs to PvE sometimes in order to level up. I would suggest to make the quests in Cyrodiil grant a lot more exp than they actually do. This way, it could give a reason for people to actually do them and thus enable some sort of feeling that I have personally been missing over the years: Exping while watching my back. I just find it a pity that people retreat to the safe realms of "PvE world" to come back later. Part of it is simply because the rewards in EXP from the quests in Cyrodiil isn't exactly stellar.
Obviously, this would attract also gankers. However, you can find them pretty much everywhere already, just that now you would know to expect them and eventually learn to counter them. Trust me, it can be done! I think it would also help to balance out some builds/classes rather than some pvp arena instance that would further split the already not so huge PvP community.
I am very well aware that this may have been talked ad nauseam, but as a not so great forum user, I haven't seen it.
Hopefully we can share ideas and have an actual constructive thread about what could be done to make Cyrodiil more lively!
Cheers and see you in Tamriel!
