I wonder if we can have a solo version of these instances, just like how they do with Waterwork and Mirror-hall. Gating epic after any kind of group content is a turn-off as the epic story has become solo-friendly for a long time. BBs, while labelling as group content, still have their solo/duo version, and the fact that players can afk through BBs still make it "solo-friendly" enough.

Sure, I can call out my kinmates or even helpful strangers to help me in those instances, but the fact that I have to depend on other players, wasting their gaming time (even if they volunteer), does not sound very casual to me.
