In a blog post
on the official site today, one interestingly timed to coincide with a big launch going on today and tomorrow (ahem), Blizzard
officially announced the start of the World of Warcraft Warlords of Draenor
alpha test. The studio cautions players that not all of the promised content is in the alpha client, so don't panic when dataminers can't give you all the nitty-gritty on garrisons. They're not in yet.
Players interested in signing up for later phases of testing are instructed to create a beta profile
on Battle.net. Applicants will be selected randomly.
