About the happiness nerf, I hadn't played in quite some time before the patch so I won't compare, but I'm doing fine actually. That doesn't mean I don't run into happiness problems all the time. But there is always some new buildings to build and get back to happy.
Then again, in all my games after the patch i managed to get notre dam. 10 happiness looks too good
