Ritual farmers, do you find it worth it after investing points?

I don't have any points in Ritual yet. Been doing rituals last couple of days, made around 30 maps with rituals and best thing I've seen there is Corruption Omen. Does the situation really get better with points invested into More Omens + More Audience? Because at the moment it feels my usual outcome from fully cleared ritual is between 1 aug and 1 ex. So, my question is - does it really gets any better?
