Lb items are rare. Make sure you run for lb . Some items are rare because many people having those items left the game a while ago. That doesn't mean they worth that much. When I took a break from AL few years ago, Ker'shal was like 4-10m. And for real now, those items are only cool as vanities. The way you get them shouldn't be impossible like LB rewards once an event is ended. This is a part of their business campaign and it should stay this way, otherwise people will no longer pay or play the game.
