From n3rfed's commentary:
Recent days have seen a flood of level 1 alts on Medivh as players from other servers make the pilgrimage to Sithilus (sic) in order to watch Ahn'Qiraj finally open. Additionally, the wait queue of this previously modestly-populated server has multiplied to over 500 and new guilds going by such names of "OPEN TEH GATE", "Aq Opens" and "Get In Queue Please" have swelled in their ranks.
Wouldn't it be more sensible for all these alts to concentrate on farming resources for their own servers? Perhaps there is some glory in being there the first time the Gates are opened, even if you didn't contribute at all yourself. There's not much Blizzard can do about it now, but I wonder if they saw it coming.
