I kinda like it? Perhaps not from the gods, but something that incentivizes more heroic tasks over a handful of posts over just one? 

Also, if its a quick play sort of thing with "jump-in" mechanics, just ditch free points in their current form.

No need for a strong god/demi-god division too, tbh, the level catch-up is already such a large gap.

For alternatives to Holy Sites, what if that was tied to the idea of worshippers giving extra might? HS allowing for more worshippers but not immediately giving them. Though that would change a lot of how they work, especially for gods that use them for the structure.

Edit: This was done before I got to read the latest posts, so I have no idea if ideas changed.
