[UPDATED JUNE 25] Prepare for Lift Off: Get Ready for Flying in Chains of Domination

This is how I interpreted the initial post:

The player needed to have 225 riding skill paid for. I don’t think any pathfinder has also granted the requisite riding skill when completed, but this is the first expansion with such tight leveling due to the squish that I’m not surprised Blizzard felt the need to add that flying had to be purchased.
