Hi, I’m from the achievement hunting community. Over the past week or so, many of us have been worried about something Yoshi-P said during the last live letter (from the unofficial reddit translation):

“・フィーストは一旦閉じる可能性がある
There is a possibility that Feast will be temporary closed down depending on how the content goes. “
(The content mentioned is the new small scale PvP coming in 6.0)
Diadem was also suspended for a time before its achievements were eventually removed and replaced by a new diadem. Will the same thing happen to the Feast achievements? We do NOT want any of the feast achievements to be removed!! Many of us aren’t done with these yet! Feast queues are infrequent, which makes these achievements difficult to get because we cannot do enough of the content. Ideally, we would like for all of the feast achievements to be grandfathered into the new PvP mode’s achievements; like what happened to the Fold’s achievements when Feast came out.
Can we get any clarification on what will be happening to these? (Please keep them all!)
