Which chromie timeline is fastest?
FYI I do not have WoD or Legion flying

They removed the pathfinder achievement requirement for flying for WoD and Legion. (It’s still in place for BfA.) Everything I’ve heard is that WoD is the fastest as it’s got a generally pretty efficient quest flow, and the bonus objectives worth a decent chunk of XP.

Wod, you should be able to fly there now…
