Book-Friend, he/him
Eh. I find the setting stuff ... unhelpful, and I was kinda surprised that for a setting based on M:tG there were so few spells (none, IIRC). I'll drop the occasional monster in, and I'll use the one subclass I wanted from Ravnica. I'm not entirely sure I'm getting my money's worth from the book, but that doesn't mean it's wrong for someone else to find it as complete as you do. Horses, meet courses.
There are one or two spells in there. They were making a concious effort to use as much straight D&D rules as possible, to make it "D&D in Ravnica" not "Magic RPG."
But, yeah, I love that sort of thing, so it works for me.
