I feel the writers know already which episodes would be weaker than others. The episode today wasn't up to the quality that other stories demonstrated.
A Rockhoof and a Hard Place could have been a major step forward in the Pillars back story. The progress the others we haven't seen since Season 7 were poorly written and trivial in context of what Rockhoof was going through. Even the pretense of the archeologist pony of being unable to cope with his intrusion into their work came off as bullshit. Had that been my site, having a 1000 year old being, no matter how different in his means of communication his memories would be a godsend! Oral history, even the way he exaggerated the stories, can be critical in locating other sites and correcting poorly documented knowledge in general.
4/10 This deserved much better than the writers gave it. However, worse is on the way in a few weeks.
