So far every BNW game where I found a religion I've done tithe. Just to play devil's advocate, though, CB still has alot of value if you can get past the mental block we all have that it is half as effective as it used to be, mostly because not only has CB been nerfed, just about ALL happiness generation has been nerfed: theaters have been directly substituted with zoos and produce 1 less happiness, stadiums produce 2 less happiness, rationalism no longer has any policies that cover happiness, the effects of Forbidden Palace are only available if you unlock Patronage, and so on. Furthermore, the effects of unhappiness have been increased; production and combat penalties go into effect at -1 instead of -10 and rebels show up at -10 where it used to be -20 (I think, never saw rebels before BNW...)
You do get a big relief when ideologies kick in, particularly Order, but I usually try to wrap up domination games before ideologies take effect. In both domination games that I've done so far, I've had to intentionally slow my progress when taking the first five capitals, and just throw caution to the wind and accept rebels when taking the final two, and that's with every happiness "out" used: pagodas/religious center temple in every city, coliseum/zoo/stadium in every city, tradition maxed out, patronage opened for FP, Notre Dame conquered, allied with all mercs and other CSs with new luxes, SW and circuses where available and circus maximus... all that still insufficcient. At that point, the extra gold was helpful but not needed, the extra 10-15 happiness would have went a long way.
