I have a handful of triumphs I am looking to finish up. Unfortunately, almost all of these involve lost sectors that are not in rotation. While I admit I have not played much since TFS, I believe some of these have not been in rotation since before TFS anyways. Especially given that people are no longer using these as the primary way of farming new exotics, I believe all of the lost sectors should either be available to select a difficulty on constantly, or as I've seen other suggest, there should be at least one legend/master lost sector per destination per day. Each day the lost sector on the destination can rotate, but at least that way, all destination lost sectors can be available.
