Don't manually gather Ancient Mana nodes ever again.
I got really tired of having to have a ton of Ancient Mana for everything related to Suramar, so I put this profile together. The pathing starts at Meredil and ends in Meredil. The path avoids the Fel, the City, Jandvik, and the top of Tel'anor (with the ghosts).
This profile will gather:
Ancient Mana Shard
Ancient Mana Chunk
Ancient Mana Crystal
If you're an Herbalist (you can get Ancient Mana from herbs and you know this already), and you only want Ancient Mana and nothing else, make sure to turn off "Harvest Herbs" and "Harvest Minerals", or you may run off the pathing.
It has been 20 minutes with the profile running and I already have 900 mana (I am on a Full population server). Results may vary.
I recommend having "Ignore mobs while in ground mount" selected.
If you run into any issues, please let me know so that I can adjust the profile.
Thank you and please enjoy.
