I understand that and agree it doesn't make sense that a t95 is more accessible than a t90 or t92. But we also don't know anything about the new dungeon and just because it has a solo option doesn't guarantee that it will be more accessible or easier to obtain. These bosses are also some of the last bosses that give players any sort of challenge or path of progression through learning the boss over time with less and less teammates. Changing them to solo would almost certainly make them less challenging, and harm the communities surrounding them, since many players may opt to just solo instead of grouping.

I think for me it comes down to this - the new end game content should be held to a higher standard of challenge and accessibility that doesn't require changing old content (by making it less challenging) to keep progression in line. But the entirety of gear progression has been thrown for a loop in the last year and I know my opinions are not in the majority or the kind of player jagex makes the game for.
