What happened to...

If you are referring to the guild perk Ride Like the Wind, we are aware of a number flight paths that restrict them from being affected by the perk. This issue only affects a very small number of flight paths and was because of how they were made and interact with certain quests (all fairly technical stuff).

All other flight paths should be functioning correctly with Ride Like the Wind, and we can request that specific flight points be double checked when reported.

In case you guys weren't aware, the guild perk to move faster while dead doesn't work properly either.

The issue you've described was hotfixed on October 4th.

Bug Fixes

The Quick and the Dead, now increases the movement speed of dead players by 10%, down from 100%.
Source: Patch 5.0.5 Hotfixes

And what about not flying as a ghost while dead in Pandaria? Really crappy in some zones like Jade Forest(specificly if you die at the Arboritum) or Townling Steps/Dread Wastes where there's quite the terrain.

Zarhym gave a reply regarding flying as a ghost in Pandaria. You can continue the discussion for that topic here: http://us.battle.net/wow/en/forum/topic/6893519708#9

Quick and the Dead at 100% was too fast sometimes. However, Quick and the Dead at 10% is Way Too Slow. Could we compromise and make it 40%?

Your concerns have been noted. I'll try to bring them up at the next meeting with our developers.
