It really is a landslide, in the alliance's favor too. On my usual server (Echo Isles) the ratio there is 2.9 to 1 which seems to translate to 6 Alliance per 1 Horde. Now I know there are people like me that have an idle alliance char and a dusty horde char as well in addition to their active DK. So maybe it's not THAT BAD, but it's still pretty bad. I'll show why with my characters on each server.

Echo Isles:
Malakor-L62 Forsaken DK (Active)
Iaespasian-L55 Troll Hunter (Dusty)
Exor'kar (Exorkar in game)-L20 Draenei Paladin (Very Dusty)

Emerald Dream:
Wertor-L10 Troll Priest (Extremely Dusty)

Farstriders:
Triaa-L55 Draenei DK (haven't got a chance to use her yet)

So yeah, it's bad!
