This might be a bit of a no-brainer, but for those of you without engineering who can't try this every 5 mins like I could (30 mins skyguard cape cooldown sucks I bet).
Heres how to get to the roof of the first building on Isle of Quel'Danas using Parachute Cloak and Rocket Boots Extreme Light, alternativly I'm sure you could use the skyguard cape and sprint, or some other form of speed boost.
Forewarning, I'm pretty sure blizzard still takes a hard stance on roof camping.

Happy camping,
