World of Warcraft's
Creative Director Alex Afrasiabi has confirmed via Twitter
that the next alpha build will shut down the Horde lines in Frostfire Ridge and open up Shadowmoon Valley in its place.
Considering Shadowmoon Valley is the expansion's introductory zone for the Alliance, I think it's safe to assume that the "new intro tier garrison" mentioned is, in fact, the Alliance-side garrison. Even though it's never safe to predict these things, it's still nice to know that the addition of Alliance garrison Followers
discovered in yesterday's alpha update was, in fact, an indication that Alliance-side testing was nearly upon us.
Having played through a bit of the Alliance quests at the Temple of Karabor during BlizzCon, I'm particularly interested to hear what the alpha-testers have to say about the rest of the zone, as well as how the blue garrison quests are both different and similar to the red ones.
