So, to be efficient the order will be:

U can fly to Moonglade from Mount Hyal

NB: I've just learned that Mt Hyjal is bugged.
It must be saved till last otherwise it prevents doing the others.

After starting the quest, found to be bugged if you do Mt Hyjal in the middle of any progress, in trying to get moonwell activated. Had to abandon and retry the quest, here is what I found working and include coords:

/way Moonglade 53.2 36.1 Lunar Preservation Quest
/way Moonglade 48.4 33.5 Moonwell 1
/way Felwood 44.0 28.3 Moonwell 2

/way Feralas 60.0 46.0 Dire Maul Moonwell 6
