Wyll getting a do-over is probably my favorite thing to hear in the Panel from Hell. I like to hear that there's going to be some conflict even among the good characters, even if you can get around that and have them become friends later. Sounds promising.
Dark Urge.....eeeeeeh I am very wary about. It's obviously heavily inspired by the Bhaalspawn of BG I+II, and also seems to be content from defaultTav that got excised and made into its own thing. It's also much more....edgy than either the EA 'bloodthirsty' scenes Tav got, or the Bhaalspawn. It sounds like it's essentially just Tav but with their own story like the Origins....but honestly, that's how Tav *should* have been IMO, and I'm sad to see that it looks like Tav will just be a complete blank slate if my suspicions of it being taken from Tav are true.
The execution.....I'm going to be honest, it's a bit in your face, isn't it? I'm not sure how much I'm going to like having to make skill checks to avoid swing off party member's limbs after 20 hours of gameplay. The Bhaalspawn's bloodlust was much more subtle.
Unknown how well implemented this voodoo fey/goblin companion of ours is going to be. We already have the tadpole in our heads, I can see it potentially becoming obnoxious. It also seems like we won't be able to have a name for our character if we go this route? in the Stream they were just called 'The Dark Urge' IIRC.
Could be bad, I'm very wary. Shame this means we won't be getting another companion like Larian indicated.
