AV in its original form was all about fighting in the Field of Strife(the middle) and gathering resources to summon your faction's BG god for alliance it was Ivus the Frost Lord who would beat the shit out of the other faction. You also helped your flying commanders escape the opposing faction's towers so they could give bonus honor and open up quests.
These matches were awesome and lasted for hours, I remember one match I zoned into played four hours then went to bed slept about 8 hours got up, showered, ate breakfast and logged on and the same match was going on.
I remember playing a single match of AV that lasted over 3 days... reports of matches not concluding between server resets. Ah the good old days. -- I'd take the time to insult your intelligence but you probably wouldn't get it.
