As of right now, the "Luxurious Toast" emote only drops in the Spire of Stars raid, and barely anyone is running that raid anymore. I think that the "Luxurious Toast" emote should be added to the Crown of Sorrows loot pool. It would still make sense since the Crown of Sorrows is on the Leviathan, plus, if it's added to the loot pool it will only add onto the existing incentives to engage with the new Raid.
