The survey is done, and after compiling the votes from the Greyhawk Adventures Group on Facebook, and both Canonfire's and Greyhawk Online's Discord pages, we have a winner by a landslide, the cleric class archetype. Cleric winning is a surprise to me because, in the last survey, rangers won by a slim margin over wizards, and clerics were in the middle of the pack behind Druids and Monks.
I will handle the clerics just like the paladins, and they will all be dedicated to specific deities and not abstract concepts like justice, light, healing, nature, etc. For these archetypes to be truly Greyhawk-specific, they need to be connected to the gods of the setting.
To let everyone know ahead of time, I will not be doing any lesser or demigods with these archetypes, and I will only be able to do some of the Greater and intermediate gods in one sitting. That being said, I will most definitely be revisiting cleric archetypes in the future in between other class archetypes.
Here are the results of the voting. I was considering just using the results of this survey to make a list of archetypes that I would use going forward, but after seeing how the tide shifted in the cleric's favor, I think that I might open voting before each new one to see what archetype is the most popular of the ones that haven't already be done at that time.
We also had two write-in nominations. Neither were native classes to Greyhawk (Although an argument can be made for psionicist).
