The problem with trying to use this as some kind of example is that it was done by old guard veterans who have literally run this content for years, including years of reaper seasons. It's not like it was some newbie who had never heard of DDO in his or her life.
I used to run elite as PD back when elite was the end game, gear was nothing like it was today, and suggesting something like hardcore would have got you canceled by the playerbase. Is it possible to do hard content in garbo gear and underleveled? Yeah it is. It's hard, but it can be done. So what? That is not the experience that the average player ever wants. There's a reason this game is a dying husk of a corpse. It needs to stop catering to a subset of a subset of gamers. Or at least it needed to. Pretty sure that ship has long since passed at this point.
Problem is, unless you want to solo, you have no choice but to participate in reaper and that means past lives. And nobody is catching up in any reasonable time frame without getting extorted by SSG. People take one look and nope right out. They have no desire to jump on this perverse hampster wheel.
