That said, these at least give me a good jumping-off point for modifying these and other themes to suit whatever use I plan to put them to.
Yeah, this. There are a few really cool themes among the articles this month (Alchemist really stands out for me), but also ones that are disappointing either because of dull mechanics (Noble) or abuseable powers (Seer).
However, I feel like they give me a very good starting point for designing my own, and in some ways, that is even more exciting.
