since they placed fated on a rotation, that was intentional, they did that intentionally, that did not accidentally happen. That was a change they implemented after DF launched. We cannot therefore say it was “supposed to have been removed”
" * And so on until the rotation is removed and all raids are Fated later in the season."
Fated was part of season 4. The affix was removed from the dungeons, so it makes sense it would be removed from the raids as well.
