Fair points, all. I'd also point out that Celtic-Germanic syncretism likely goes back even farther, since in the earliest days of proto-Germanic speakers, the Celts were their immediate richer, more powerful, higher-status neighbors - artifacts like the Gundestrap Cauldron suggest at least trade/raiding relationships, and especially in the period of Roman control of parts of modern-day France, Germany, and Britain, we see Celtic and Germanic artifacts cheek-by-jowl, along with signs of syncretism.

As for the pantheon thing, I agree that the idea of "a pantheon," in the form of a unified, static body of Gods worshipped in the same way and with the same tales told about them is almost certainly over-projected onto every body of myth/religion we have, even the Greeks and Romans, but especially those less-well-documented and less-unified (like the Germans and the Celts). That being said, I tend to think that there were more strands of continuity than the most extreme forms of the "no pantheons" argument allow. To put that in plain, down-to-earth terms with an example, I think that the cult and tales of *Wodhanaz, Wotan, Woden, and Odin were meaningfully similar beyond a name with shared etymological roots. I also think the "Odin was just the God of the warband" argument at times goes a bit far (not saying you're asserting that here), and I tend to think that though, as you say, He was the warband's favorite God, that doesn't mean he wasn't recognized/worshipped/sung about by other groups of society.

All that being said, yeah, the on-the-ground religious picture of the Germanic-speaking folks was almost certainly more complicated at any given time than we tend to assume, to say nothing of changes over time, and different Gods, tutelary spirits, tribal totems, and so forth very likely played a bigger role in everyday folks' lives than it's easy for us to guess at. Luckily, polytheism neatly allows for this kind of variety, so I'm not too put out by it. For myself, all I can say is that I had a moment where I realized how almost comically apt Woden was as a God for me to worship: I signed up for the Army to try to join the Special Forces, I broke both my feet in the attempt, learned a lot about myself and the world from the suffering that resulted, I mostly try to get my way in the world by speaking, I teach others how to get what they want through speaking, and I'm always restless for new knowledge, including magical knowledge. Luckily, no insane furies just yet, nor situations where that would be useful.

Cheers,
Jeff
