So it looks like class DCs have a proficiency modifier now, based on the details in #58. That’s different from the playtest, right? I think class DCs before conspicuously left out a proficiency bonus, which I always felt was odd.
My search fu turned up this thread, which asks the same question I've been thinking lately. Has there been any official clarification on whether unarmed attacks or fists count as weapons for various effects/feats/etc.?
