Well I'd put all of them in line for the nerf bat to be honest.
- Magnus - +25% from chops (if not change this ability entirely) and make it no longer a Tier 1 promotion
- Earth Goddess - Should generate Faith from tiles of Breathtaking or better considering there is zero investment required. All the other pantheons at least require an improvement (mine, pasture, whatever)
- Goddess of the Harvest - Should generate a flat Faith bonus, not scale with chop strength. +15 or +25, nothing much more than that. Compare to the belief that offers +50 Faith for taking a Barb Camp. Did they really intend a chop strategy to grant hundreds of times more faith than that given the minimimal investment?
Some of the other pantheons need buffs too, but this takes care of the baseline.
