It really depends on how much you want them to be distinct. Personally, I would have had Tieflings, Aasimar, and Elementaari all be distinct heritages, but that's not the way that A5e decided to go, so it's a matter of taste.
Okay, Here are my thoughts
Savant Archetype: The Detective
I personally don't see why this couldn't have been described using the Perception and Investigation skills instead, but on its own it's not bad.
Again, I think it would be simpler to describe this in terms of using Investigation and...
Mostly because they cover the same groundas these archetypes, and so I was wondering whether or not you had looked at them first, or built these from the ground up.
I’ll have to think about how I want to proceed, and I have GPG articles to focus on first, but I’ve been looking for something worth putting out a 3PP for, and an A5e EoM book sounds like just the thing!
I have now purchased and mostly looked over both, and I’m glad I did. Elements of Magic does have some useful benchmarks for translating the system to a d20 model, but overall I found WOIN to be more streamlined and easy to approach.
I haven’t played with an A5e bard yet, but my issue is partly that it limits the kinds of characters you can viably play. Sure, you can switch to another art specialty, but what if you just want to be on the strings for the sake of your character concept?
