Unfortunately, I couldn't finish the live stream due to a real life interruption 🙁 I hope I will be able to see the rest of the panel this evening.
But from what I have seen so far, this is so, so much more than I would have ever expected.
I'll write only about the parts of the panel now that I have seen that seemed to be complete, I'll add the rest later when I've seen the whole panel.
I think the new character creation interface is much better structured than before. And the customization options are awesome - we finally have a stronger body type option, we'll have freckles and age sliders, piercings, customizable horns for Tieflings - and scars (I've been waiting for scars since patch one). I'm quite sure that I have forgotten a lot of things - I should have been taking notes.
I really like that each class now has a little animation.
Warlocks will now have the possibility to interact with their patrons. I'm now sure that my second playthrough (or maybe even my first) will be a Pact of the Archfey Warlock.
And we will finally wear more comfortable clothes when we are in camp - sleeping in full armour was always a bit immersion-breaking for me.
I like that when you play as an origin character, you'll learn more about your character's backstory in their dreams.
I'll write about the more important parts once I've finished the panel, I want to get the full picture first.
Oh, and the tressym was very cute. (And Vlakith was just as scary as I had imagined her to be)
