i would like to have an option to flag a enemy guild as a war target.
1. Declaring a war target (cost x gold)
2. Keeping the war target active (cost x gold per week)
3. Makes your war target guild always appear in the same Cyrodiil battle where your guild goes. (would work like friend/guild list => same campaign).
also it could be a good idea to add a hostile list, it would basicly be like a friend list but you could tag a enemy player in it that would be with you in a same Cyrodiil campaign(if he has not been saved). but only if he has no guild i think, if he would join it as part of a guild he would drag his whole guild to that one Cyrodiil campaign or is that a problem ?
- - - - also as having a hostile list if the game has quests between alliances, perhaps assasination cloak and dagger quests and if the other player is on a PvP quest like that you could perhaps hunt the players that are in your hostile listing ? (just an idea)
These are some ideas i have or wants, i am not like stomping my foot down and demanding these but i think it would be a good thing if not yet added.
it would basicly make it possible to some guilds effectively compete for Emperor seat and perhaps make some flavor happen in the RvR

But as always it could be used to effectively give Emperor titles by having major guilds participating in the same campaign all over again and again, thus i dont know how that is evaded. but 2000 players divided in 3 factions per Campaign at Cyrodiil... i dont think any guild can effectively deal out emperor crowns with those numbers or can they ? hmmmm
