Bungie please consider adding the seasonal exotics to Raids and Master content. Make the drop rate in Master higher than normal raids but consider bringing back the Calus Ghost that upped your chances to make normal near master.
When I have time to play I prefer to attempt raids and other triumphs like grandmaster nightfalls. They are challenging, and fun social time. Doing Master lost sectors solo over and over sucks the fun out of the game to me. You can leave the lost sector grind option in but please consider adding the seasonal exotics to the loot pool of other difficult content for those of us with less time to grind. E.g., Trials, raids, master dungeons.
