Its exactly what they did with the Shadowlands Alpha. Torghast was so much fun in testing, people loved it but slowly Blizzard tweaked and nerfed and added and now we have a mess that people will do anything to avoid.
Thats whats happening to Dragonriding in Dragonflight, by the time it launches itll be so hated that we’ll all just be begging for Pathfinder to come back and give us the same boring flight mechanic from 20 years ago.
