Today in WoW is like a tiny miracle for collector's this expansion. So many rotating things, especially with Korthia, and having that on the homepage makes the collector life easier.
Wow even with HandyNotes I missed this one even though I did the Achievement. (Probably because it disappeared once I completed it and I missed the note about needing to see a vendor). The amount of "hidden" stuff is crazy. At least there is HandyNotes and Wowhead, but it still seems a little ridiculous that there are so little indications in game for so much of this stuff.
The amount of anima you'd need to get all the collectibles is just insane though.
This is more like part of the "not easy to collect" list.
@Nymrohd Korthia gives you absurd amount of Anima. Plus lossless Anima transfer via heirloom.
People need it to happen overnight with very little to no work involved. You are 100% correct about the plethora of anima you get in Korthia but it will never be enough to please the entitled ones.
