Part 1 - We will complete the Battle for Azeroth Pathfinder achievement. This increases your mounter speed in Kul'Tiras and Zandalar, for now! It will be the step towards flying.
Part 2 - We will earn revered status with Rustbolt Resistance and with either Waveblade Ankoan (A) or The Unshackled (H). These are Nazjatar and Mechagon reputation factions. This service also unlocks the Wonderwing 2.0 mount!
 
ETA: 1-4 Resets (Flexible, depends on your current reputation)
Need have 370+ ILVL
