Me and my guild do alot of small scale ganking and from what I've found its a very reliable way to gain AP. I am Soulstorm Decimus on Wabbajack and I joined the server around a week and a half ago on AD and I am already in the top
From what I've found small scale skirmishes or ganking is a much more effective way to gain AP than just zerging. Unless your using a firepot.
Anyways I made a little montage of some of the ganks we have done. Enjoy.
