And if she had fun, great. It then ended up worthwhile content for her, at least when/as encouraged by friends, etc. But that doesn't mean it will be for everyone. Not everyone will enjoy themselves on the way to those successes, or possibly even even in just from the first clear's run onward, to make that worth their while, especially under those circumstances. Just as not everyone will want to do DD or Exploratory Missions. (See also the reaction to WoW players being forced to do the equivalent of each just to be competitive in raids.)
For instance, I straight up don't like most battlegrounds in WoW, instead preferring 2v2 arena, and would rather prog M+ to well above the difficulty of some Mythic raid progression friends would deem undue masochism than doing Mythic raid progression myself.
