I’m digging through Discourse’s actual patch notes, but I am admittedly not super technically inclined, so I may be missing the proper terminology they’re using to relay that change. But any mention on the forums looks to have taken place after Discourse’s 3.0 release in mid-January.
But just with the Vrak post, it’s mentioning that it is earned all on one character (unless there have been further updates since) to meet that marker, and that the upkeep to maintain that TL should be on that character - but that the perks are shared. Or should be, rather.
