Баги, куда же без них.
Выявленные на данный момент на американских серверах (возможно, к запуску наших серверов, часть уже поправят): People are reporting inability to zone into instances, often times met either with the dreaded "Additional instances cannot be launched" error or just flat out lagging out so long that they're ported back to Dalaran or wherever the system decides to drop them, entirely unable to enter the instance.
General Issues
Logging out inside a battleground and logging back in after the BG is completed will cause characters to be unable to queue using the Looking for Dungeon System.
Spamming the Auto Attack button causes the character to play the attack animation even though no actual attack is done.
Dungeons & Raids
Escape from Durnhold - At the end of the Escape from Durnholde instance Erozion teleports you back to Caverns of Time rather than where you entered the instance from.
Halls of Reflection - Player will get disconnected when running up the ramp to the ship.
Quests
Horde players do not receive a parachute when the Kor'kron Troop Transport is destroyed during the quest, "Assault by Air".
Classes
Druid
While swimming in Cat form or Travel form players nameplates are clipping through their model.
Mage
Mage Summon Water Elemental does not fully function as a permanent pet when glyphed with Glyph of Eternal Water.
Paladin
Avenging Wrath and self cast Lay on Hands cannot be used within 30 seconds of each other.
UI
* The dungeon finder visual UI will sometimes display inaccurate class archetype counts.
* The group "guide" is called "Party Leader" in chat.
Вопрос только в том, сколько ждать - если между всеми крыльями такой перерыв будет - это жесть))
