There is a 10% xp bonus that is awarded to players who are on the lowest scoring alliance.
I am wondering if this bonus will stack with all the other xp boosts?
I would also like to know if this bonus applies to all quests in cyrodiil?
If my understanding is correct then players can earn up to 50% more xp using this, a sub, rings of mara, a group, and a xp pot while in cyrodiil. Is this correct?
If this bonus applies to all quests then it might be beneficial for players to complete the cyrodiil town dailies in another factions buff campaign. Even if there are more players of a different alliance in a buff campaign they are essentially discouraged from tampering with the keeps since they would lose their xp boost.
Maybe this boost only applies in your home campaign, I don't know.
Anyone know more about this? Is there an equivalent PVE boost that will allow players to gain 50% more xp for everything outside of cyrodiil?
