Yeah, I've been wanting a more polished Israel civ myself. I've been too busy with school to do them myself, and even then I'm helping Pouakai with African civs first, so it's not something I'd have time for. (Plus, I have a 90% complete Hittite civ to finish first - which is why my religion mod has a programmed Hittite preference. It's been sitting on my computer for months, I've just never been able to get their ability to work the way I want). In the next version of the Historical + Schisms mod, I've already set the Goths to Forn Sidr as once you split Christianity there really isn't a historical option for them (and I'm not going to add Arianism just for a mod civ that most people probably don't use). Otherwise, I normally set the religion based on the leader, which for Alaric was Arian Christianity. However, you're right for the same reason I decided to set Denmark to Forn Sidr; there's frankly too many default Christian civs and the religion game needs diversity. I'll get it in the next update. (Coincidentally, I need to update my Goths civ as their UA isn't exactly balanced. I just need to find time to do it).
