The note says with next update, but I didn't see anything in the patch notes. I hope it's getting fixed, I would like to group with my lower level guildies again to help them get stuff done!
Mentoring being restored isn't exactly an update. We can trust that they held to their promise and will restore it when they said they will If they don't then get your pitchfork ready
Nothing about inheritence merchants being put back in either - but lets hope they just didn't mention it and put the NPCs back in.
In the notes! GENERAL Fracture, the Inheritance Merchant has returned to Freeport and Qeynos. Time-Locked Servers Mentoring has been re-enabled on Time-Locked Servers.
