2. Bards are cheaper in hammers than the stories they can build, so build bard then use it to build story. Or just reduce the cost of stories (or increase cost of bards) so that they're equal to avoid excessive clicking.
This is as intended. Bards come much later than the buildings and are for catch-up. They represent the fact that the building should be much cheaper in the later era. Or you could just wait until you have Entertainers and build one Stories building in a city with the Story to get the effect in all your cities.
I tend to build the Story buildings with subdued animals in cities that need the education and then save the corresponding subdued animal to build the Stories there later. If I can't do that I will wait until I get the Entertainer in the later era.
3. Tamed animals used to build buildings is a cool way to help out smaller/newer cities; but getting a (relatively) expensive carnival for a cheap animal may be too much. Once I get a Tamer built I never have to build another carnival even for advanced cities.
Again as designed. You could have built the carnival with a cheaper subdued animal. The tamer is a bit more expensive way to build the buildings that the subdued animals built.
I am only about half way through changing the tamed animals, some are a bit easier to get than intended still. If you did not build the buildings necessary you wont be able to build the tamed animal. It is part of the way to get the AI to use the subdued animals in their cities.
