I'm totally on board with your suggestions, my next adventure will focus on the Domain of Greyhawk for now, especially the Free City.
On another note, I wrote a new blog entry about the Greyhawk's Human Races. So if you want to make a Baklunish or Suel character the same way you make a wood elf, you may do so now.
I would love any feedback, also if you have suggestions for new Mechanics Mondays or Fellow Fridays, just shoot them in my directiom.
