A new build, number 9464, went up on the PTR last night for the perpetually predicted, not quite here yet patch 3.0.8. The changes aren't huge; for the few list, you can check out MMO Champion. But there are a few that interest me.
Scrapbot repairs equipment, as we discussed previously.
Vampiric Blood, which got a huge buff in early 3.0.8 builds, has been taken down a little bit, although still better than it is now. In the latest build, it temporarily gives the DK 15% of his maximum health, and increases the amount of health generated through spells and effects by 35%, for 20 sec. Previously in 3.0.8, it was 20% max health and 50% increased healing. In live, it's just 50% increased healing.
