Happy to say that this feedback is outdated, as this has been addressed and improved vastly since the Early Access days.
Naturally it still happens on rare occasions and specific scenes could use some range reductions, such as;
The Grove fight with Zevlor or Minthara, Mayrina (if the masked people are dead, if they are alive then they all wait until they're talked to), the Githyanki patrol pulls a random party member into the scene as Kith'rak Voss flies away
But I've been playing for over a hundred hours now and apart from these few scenarios it no longer feels like an issue as I don't have to fight my party members to be the one who speaks. The game now really prioritizes the main character when everyone is together and I'm happy with that.
Naturally it can use more improvements to reduce the massive dialogue range for some troublesome scenes, but overall it feels great now and this feedback has run its course in my opinion so
moderators feel free to lock this outdated feedback thread.
I hate it as a druid. If I don't wildshape out into human before a fight ends, dialogue always goes to companions, and even then it also seems proximity based, like with Hope after Raphael talking to the nearest companion. It's so annoying.
If I wanted the game to address the companions, I would have rolled an origin character.
Even then the game prioritizes the camera on origin characters over the custom Tav. For example, when Voss is told about obtaining the Orphic Hammer, if Lazael is in your party, he will talk to you but always face Lazael while talking, as if it had been her he was directing it to.
