So, I have been messing around with this for a few days now, and I found a way to get to the instanced Thousand Needles via Zul'Farrak.
This method works on 4.3 live and is very easy and extremely noob friendly.
Requirements:
+85 Warrior {May be possible for a Goblin, Untested.)
+Some sort of Slow Fall Noggenfogger Elixir - Spell - World of Warcraft, Skyguard's Drape - Item - World of Warcraft, Flexweave Underlay - Spell - World of Warcraft, etc
+100% speed mount or Nitro Boosts - Spell - World of Warcraft
I know there is tons of videos out there about exploring ZF, but I haven't seen a solo method for 4.0.3+ and most require a mostly dead wallclimb, and/or another person.
This is a solo method for Warriors.
On a side note. when I released I ended up in Westfall. :|
