It's undeniably a competent story and has the charm that you would expect from a 2013 work. I like the idea of Luna's arc, which is arguably the focus of the story, but it's little more than competent.
I can't think of any stories that successfully merge MLP with tabletop RPGs. My consistent recommendations for people who want good tabletop RPG (specifically, DnD) fiction are Rich Burlew's The Order of the Stick and Sir Poley's Harry Potter and the Natural 20.
