Authority seems fine. I still prefer Progress but it's fine and not broken. Tradition is now the worst early tree (unless you're Korea/Arabia and/or took mastery, in which case it's probably broken)
Pantheon wise, God of the Sun is the worst pantheon in the game, with only +1C+1F per only one, rare resource (Wheat) and a mere +2Food in Granary. I never take it and an AI who takes it inhibits both his early and late faith growth, all for a silly 2F. I made some suggestions on this one already before, like maybe +1Faith or Production or something for every two worked Farms, or just +1F/+1F from Granary. Even on Wheat starts I never take it, it's too weak.
Besides that it's sort of balanced, but perhaps Ancestor Worship should get a tiny nerf to faith to compensate for +1F+1C per city council? It's just my opinion though but it's pretty easy to get it to give you the most F from all the pantheons (especially now it isn't even weak early on unlike it was previously) and it's no longer even weaker early than others (if anything it starts just as strong or stronger and only ever goes up).
UA I can't say, didn't play any of the changed UA civs yet, been playing new games lately so had little time to deviate from my fav civs.
