Last Wish still gives powerful gear, so that's not likely gonna happen. I wouldn't want it to happen either. Raids are supposed to be difficult AND mechanic-based and all of Destiny 2's raids have hit those descriptions quite well. Yes, we are guardians, but when we raid, we go against gods and other, more powerful, Paracausal Entities than ourselves. To get to a point where we "one man" them would be a disrespect to the lore. If you're upset that we have to find a full fireteam for older raids, look at the LFG. People were running the old raids (The Leviathan trio) all day yesterday. If you want a difficult challenge that you CAN solo, play Shattered Throne. It's available until Tuesday reset.
