Clearly you don't use this mod, because there is no spawner, and only one gorgon per temple, so you cant make a farm (this was done to prevent grinding). Also, the temples are very rare. Heck i searched for a whole hour IN CREATIVE MODE and still didn't find one. You second point still stands, but keep in mind that you have to find them first. So it is really you who should try harder.
lol alrighty. I've got better things to do with my time than argue over the validity of a farming method on minecraft. I'll give you the win. Later
EDIT - I see that you're very interested and involved in this mods development. I'll be porting a mod I'm overseeing called minefantasy to 1.12 and placing integration for ice and fire into it so keep a lookout for it.
