This content is the lowest common denominator. It is the easiest baby mode raid. You do not get end game gear (except for weird kinda quest rewards you get for beating the last boss on any difficulty). This is literally only there so someone who doesn’t interact with people or cannot physically do the raid for disability or skill can expirance it and see the cutscenes. This is inclusion not erosion.
There is still a large community around the harder contents and if you want real gear you have to still group.
I almost always played solo because I liked exploring and crafting and doing things at my pace. Whenever I had a group, I felt like I was pressured to move move move and finish as much as possible without absorbing the environments or reading the matching story lines.
I was able to finish a few of the low level instances, but was rarely able to find a group to run with and thus usually just skipped over any quests that required them. Sure, picking up some legendary gear would be nice, but I would have just loved the option to stroll through these quests on my own.
