With all due respect comparing the ICONS Hero Pack is not a fair comparission.
The reason why is we all paid Dan $15 - $25 per character art piece, with the agreement that he could use them for publication. I pulled my Zenith Characters once Adamant decided to publish it for sale.
There is no way anyone can compete with a product that;
A] Has all the art paid for by the users (in this case a minimum of $1800 paid to artist).
B] Is created by the artist himself, thereby making his art issues his own and not paying out of pocket to someone else and then waiting, waiting, waiting and waiting for the art to arrive in a vacuum.
Now, as to you issue of value vs. product. Yes a series of plot seeds would be a wonderful thing, but again this is not the item I am asking about (though everything I produce has Hooks in it to make for more use than just a bunch of stats). Though like the idea of locations it is something to think about, down the road.
Based on your price comparisons ($4 for 30 villains or $1.99 for 120 villains) I shouldn't expect you to purchase "Zenith Comics Presents: Supervillains! Vol. 1" which will provide 11 villains for $1.99? A shame, though I totally understand you reasoning for your price points.
So based on the feedback I have seen for this idea (single hero/villain dossiers) I probably can't seen myself producing them. No one seems to like the idea and that's that. No harm no foul.
