I love the new controllers! So much better than the old ones!
I’ve noticed the angle discrepancy as well. The hands definitely seem to be 30 degrees or so off from the actual hand axis - this makes guiding spells with the off-hand really awkward (you point your actual hand at the floor)
In the 20ish minutes I played last night, I didn’t notice as much of a discrepancy while using the Bard mallets or the wand though. Either the angle is set a little differently for each weapon, or some weapons have a wider angle tolerance where they still work.
Edit: After a little more playing, I have to hold my wrist at a 15-20 degree downward angle to consistently get a flat plane for casting spells. I think there is just a wider angle tolerance for some of the weapons…
