Bungo isn’t in the business of giving their paying customers what they want. Don’t expect them to care. The Whisper exotic mission was in both the weekly rotation and in the pinnacle rotation while they’ve put Encore in both weekly rotations. They’ve also removed Encore twice also as people enjoyed playing it. The people running this game don’t want you to enjoy their game by getting the loot you want. I would love to see Your exotic mission also because ai don’t have that one either. I do have almost every part needed to craft the Choir of One. The only part I need is the craftable version of the weapon. Xur sold it just before the launch of Edge of Fate but there’s no harmonizers in this current season. Don’t expect it to become available because the head bingo is busy admiring his car collect that he could afford after laying off his employees.

Portal missions have been rotating week to week as bungie does their “slow rollout”. It’s probably coming at some point, I’d just keep an eye out for Derealize to appear there. I have no idea how to get the upgrades for it now though

The exotic mission in the legends tab should rotate weekly.
