Fact
Horde players are attacked on sight in open-world Dalaran; City of Dalaran dungeon access is unaffected, and the Horde Dalaran Sewer Key questline no longer grants open-world access. Horde characters can no longer gain Kirin Tor reputation. Battleground Marks of Honor stack to 30 (was 20). (Oct 15 beta development notes, as relayed by Icy Veins; Blizzard forum post not read directly.)
