I have expierienced this a lot too. I actually want to identify with my PC. The way it is now i can't really do that. To make use of other party members skills or attributes you need to have them initiate the conversation. The conversation stays the same though. Feels a bit awkward. I would suggest having only the PC initiate conversations (or combat:)). and then Dialogue options for other party members like we have now for race/class/skill etc.
I guess i am not the first to suggest that.

On the other hand i feel that the dialogues as a while miss some consistency. Apart from the fact that, if someone answered me like the NPCs do often i would turn away and leave, the whole conversation i have expierienced till now is somewhat ...negative. NPCs are more friendly and respectful sometimes. The other party members just follow their way without ever thinking of the consequences. I really don't know how to put it correctly.

I started a gith to see the interaction betwenn la'zael and the PC and i was pretty disappointed. In some conversations there is no change to other races. then she acts totally superior but in other moments you can cut her off without any big consequence.

Dislike or missing trust is normally no reason for open hostility. The Party characters want something from another. Mostly. But to me it feels like the PC can go to hell for what it's worth.

Am i alone with this?
