PTR Notes: Patch note watch 2/28

As Matt Rossi is analyzing in more detail, the attunement requirement for Karazhan has been removed, although at least one person in the raid does need to have the key to get in the door. How do we know? New patch notes.

Here, in full, is everything that's changed in the latest iteration of Blizzard's official test realm patch notes, brought to you, as always, by the power of diff. Much of this has been covered on WoW Insider already, because Blizzard is slow to update the patch notes; the stuff that looks new to me is in bold (which in this particular case is only that the new Mortal Strike-esque effect on Flametongue Weapon applies to Flametongue Totem as well).

• Removed: "The benefits of drinking out of combat have been delayed. It will now take five seconds before the full benefit of the mana regeneration will come into effect." (now restricted to arenas only)
  

• [Druid] Lifebloom will no longer cause error messages when interacting with Spellsteal or while the Druid is under the effects of a Mind Control.

• Mage

• [Priest] Added "reducing the mana cost of all spells by 20%" to the new effect of "increasing their spell haste by 20%". Does not stack with Icy Veins or Bloodlust/Heroism.

• Shaman:

• Warlock:

• PvP:

• Dungeons & Raids:

• Items:

• Elites in Blade's Edge Plateau Regions: These creatures now have an increased chance to drop rare depleted items.
