PTRs going down for another new push

The public test realms have really been going offline a lot over the past week or so. Though it seems like they just came back up, and we don't even know what the current changes are, aside from a Shaman de-nerf, they're going down again, as of a few minutes ago (noon PST). Hortus merely says the downtime is "to apply a new build," and the patch notes still haven't been updated, so I can't tell you what's coming, although tipster Khanmora's guess that we may see the promised Life Tap modifications is one that I share. The downtime is expected to be between four and six hours.
