I don't know anything about D/N cycle or the conversation skill check thing, but they did say from the start that multiclassing would be a thing, so I just figure that until they say something to the contrary, it's gonna happen and is simply being saved for full release.
I think that for me the biggest stumbling block is the implementation of camp scenes. I firmly feel that a) some scenes and exchanges should just happen out in the world. There are a couple that do, but I think there are a few more camp scenes that could happen on the road instead, and b) we should be able to trigger more than one camp dialogue at a time. Especially when it's not a party-wide scene like the whole 'feeling sick' situation. And of course Larian needs to do a better job of keeping the scenes from being so easily missable. That's such a glaring problem that I'm hoping it's something they're working on behind the scenes.
