This is a fairly straight forward glitch combining Shunt1900's "Offline Mode" and a bug in game to allow for flying in any zone with complete disregard for No Man's Land, Breath, and Fatigue. The flying is only currently applicable for Druids however, if you are not a Druid skip to step 3.
For Druids:
1. Glyph into Glyph of the Stag and activate Flight Form.
2. Navigate to a zone within Draenor (TaladorIntroZone also works for this)
For Everyone:
3. Log out
4. Click on change realm and select the realm your character is currently situated on.
5. Very quickly tap enter twice when the realm is selected to cancel the attempt to reach the realm and wait 1-2 second(s), then proceed to press enter once again.
6. If you've done this correctly your game will be stuck on "Logging in to game server", press escape twice to navigate back to the login screen
7. Log back in to the game and onto your realm, Druids will be able to fly in Draenor at this point, and navigate to any zone in Draenor.
8. Use a speed enhancing boost or a mount (Optional)
9. Spam click the macro as posted below and it should disconnect you into 'Offline Mode', you can check this by trying to cast a spell.
10. Explore, due to the fact you're in offline mode the following will not affect you: Breath, Fatigue, or No Man's Land.
Macro:
/run for v=1,500 do for i = 1,GetNumFactions() do SetWatchedFactionIndex(i) end end
