Ok so today I was on my new lvl 80 so it didn't have flying mount yet.
Now then I decided to take the flight to Orogrim's Hammer (The flying "camp" in Icecrown) to be faster.
The ride provided however flew almost over the Tournament Grounds. I relogged while flying and when I logged back in I fell down and died. I ressed and was a the Tournament Grounds already, about 10mins faster than normal.
Steps;
1. Talk to Sky-Reaver Something in the area in Dalaran where u can go on flying mount.
2. Ask him to transport you to Orogrim's Hammer. (This is the Horde ship, ally prolly talk with another NPC).
3. As you approach the Tournament Grounds, press /logout and wait for the 20sec timer. Time is so that you logout and close to the grounds as possible.
4. Log back in.
5. Ress and walk a little.
Ofc you should take off your gear before you logout since you will die if you dont have slow fall or alike.
