I would suggest to increase the max level for the God's shrine to 55-60 and expand Mythology research to give us more percent to the shrine or maybe let us build statues of the gods to get extra % boost.Or the best of all,all together!
I don't think that this is such good idea. the shrine is already the most important building and making it even more OP is counterproductive.
Perhaps add a new building that you can construct instead of the shrine that would boost other things (not resource production). perhaps ship speed, scientists production, and other non production building, so you would have to make a decision what you prefer.
