I don't know about you guys, but me personally with the Tamriel One Update wish Imperials or Players in general, could choose to not have a main alliance, or just join one later. This could either mean in Cyrodiil you can attack anyone and they can attack you, or you can't attack anyone and they can't attack you. This I feel would fit the Imperials mostly. Expanding quest possibilities in Cyrodiil, with having the ability to not be loyal to an alliance, seems like a fun concept to me. I don't mind if it's a free for all or you're just simply protected, but i think it would be a nifty little option to have.
