I've been aching to server transfer from my Low Pop server, Firetree, to one of the high population servers.

If I do, then I'd like to join a horde multiboxing guild. Is the "The Zerg" still active?


The main thing holding me back is the cost. I have a lot of toons and it would be cost prohibitive to transfer them all.
Has anyone done this? Is there a cheaper method?
