Sigh ... thanks for the answers SunGardian, Tarloniel, Zarna (and everyone else I may have accidentally missed). I'm really wondering
how Larian works ... I mean, why coming back to polish some things at the end when you could do things well from the start, and doing so does not require more work ? (Ok, it depends how their code works ... if it's not greatly organised ... it might be better to avoid giving the Deity feature to any other class if the code for the feature is to be reworked, and classes "accessing" it actually need a copy-paste of the code, instead of a pointer/fetcher to it.)
Sorry. They don't. I guess all druids worship... nature? Or something? I haven't played 5e, I'm not clear on how it works now.
1) Druids can worship any God but most have a direct tie to nature. They draw from the power of nature itself, so their power is their own but they can worship.
Druids started out as Clerics-but-different, being essentially modelled after the Celtic priests of the same name. Then the lore of the FR evolved, but Druids have remained Divine Spellcasters. To the question "where do your spells come from", Arcane casters would answer "study" (or "it's innate" in the case of Sorcerers), Divine casters would answer "from my god". For Druids, those would be nature gods.
Nowadays, the gods are not necessary. For Clerics and Paladins, you can say that they derive their power from faith in an ideal, philosophy or cause. Certainly, I would have assumed that you can provide a similar god-free answer for Druids, even to a GM whose setting is the strictly canonical FR. As a matter of fact, there's always been the concept of Shamans floating around, often attempted to be captured/implemented as yet another class, and the answers "spirits" or "drawn from direct, intuitive understanding of the forces of nature" have always also been there, including for Druids (and Rangers). So I just checked the PHB, which confirms all that :
Druids revere nature above all, gaining their spells and other magical powers either from the force of nature itself or from a nature deity. Many druids pursue a mystic spirituality of transcendent union with nature rather than devotion to a divine entity, while others serve gods of wild nature, animals, or elemental forces.
So, currently Larian has created a whole Grove of Sylvanus-worshipping Druids. If I understood the trailer well, your PC Druid can become
Faith Warden. So ... hm ... either they consider that a PC Druid must be of the "direct connection to nature" type and doesn't need any god, which would make absolute total sense with their depictions of Druids, or they they have never heard of Chauntea, Mielikki, Eldath, quite a few others gods as well as the "direct connection" type Druids and they assume that all PC Druids worship Sylvanus. Both of these choices would be poor ones. Or, as I hope, they just haven't gotten round to giving Druids a deity yet.
Druids in 5e don't necessarily have to worship, but a lot do worship various nature deities, same goes for rangers. Paladins can now swear themselves to causes, rather than gods, but again, many still worship gods. Its about giving people options to play the kind of character they want. Also it is a side effect of getting rid of divine champions and blackguards as classes, paladin had to broaden its class portfolio. There's absolutely nothing stopping you from going old-school with your paladin, but you have options.
It's why I think everyone should have the option to select a god, because lots of people still make characters that are religious, even if they aren't playing a cleric, or need it for their class.
Absolutely !
Everyone should have a Deity attribute. And everyone should be able to choose "none" for Deity, including the Divine spellcasters.
