Just finished heliostat also. It was a good exotic mission. I liked how it got harder for the intrinsics and had some puzzle finding. I just wish in fireteam finder as a goal, it would list what you are going for like intrinsic 1 and so on. Reason being sometimes you have to get objective A restart and get objective B. A lot of times people are going for objective A but you want objective B. There is no way to let people know you are going for objective B. Like they have tier x loot listed.
