None of the routes listed for Horde getting to Karazhan work for me. =(
Thrallmar Mage needs to actually have the ability to port that you claim you guys gave him. He does nothing but promote tourism in Outland. Fix please.
Thrallmar Mage does NOT offer a port of any kind.
You can use portal for dungeon pet battles in Dalaran (Broken Isle). Hordes can port to Deadmines and fly to Karazhan.
The Honor Hold mage at the entrance to the Mage tower does not send you to the Dark Portal you need to get to Outland. He sends you to WOD Stormshield. There's a portal to Shattrath upstairs.
As a max level you can't travel from Blasted Lands to Outland anymore. Nothing happens when you attempt to go through Old!Dark Portal.You can also mention portals to warfronts when a faction happens to control them.
Horde: Caverns of Time portal is under the main portal room - just before you run out from main portal room, there are 2 lit torches on the right - that leads you to the lower portal room with CoT port
My alliance characters can talk to their mage at the bottom of the mage tower, where the portal used to be, and be teleported to Blasted lands.But the Thrallmar mage in Orgrimmar won't teleport my horde characters anywhere.
Currently, you can no longer travel to Outland via the portal in the Blasted Lands (even if you go to the old one).Unsure of why this is the case, I asked others and they were baffled/confused by it as well.It seems it probably bugged out in a random patch.
Thrallmar Mage doesn't port you ANYWHERE unless you are doing the intro WoD stuff. The only way to Hellfire by portal for Horde is port to Shattrath and fly all the gdmf way to and through the Dark Portal. The closest thing to that would be get a mage to port you to Stonard. No idea why Blizz had to make something that was so easy into something so difficult.
For the Dalaran Crater, if you use the mentioned method as Alliance, flying from Twilight Highlands to Aerie Peak takes 6:56 minutes, while flying from Iron Forge (portals: SW > Boralus > Iron Forge) there's a straight route that takes 4 minutes flying.
For Horde, the Thrallmar Mage by the the Shattrath portal takes you to Hellfire Peninsula, not the Blasted Lands. Once arriving, you cannot use the Dark Portal to go to the Blasted Lands for some reason. Trying to get to Blasted Lands this way doesn't work.
