I played it. It's a great map. The story is engaging.
But the map itself is very easy.
The only difficult battle is against the fairy dragons. You suggest accumulating golems to defeat them, but a combination of Titans and antimagic works better.
I liked the spirit of adventure, when it became possible to visit any island in any order. I laughed at Insmouth. Overall, I enjoyed the map. But it lacked a challenge.
