i would argue that it is very close to DnD because if you have an encounter with a group everyone gets to talk to the baddies if they want to except someone of the groups decides to attack instantly.
Another example would be if the group meets some lord and get a contract. There is not only one person talking usually but the group as a whole - with the suggested system this would be possible.
Technically, SWtoR system isn't the group talking as a whole. It's still only one person talking. It's just a dice roll to choose who, whilst allowing everyone to have their associated dialogue option side effects (Meaning their morality isn't screwed over by someone else getting to roll their preferred dialogue option)
Solasta is more of a "The group talking as a whole" as each dialogue option is voiced by a different character. Though I'm not sure how this would translate into mulitplayer (As the single player mode of the game has you create your full party and then separates the multiple options in dialogues across them)
The SWtoR system seems fairly decent for multiplayer video games. Given it provides equal opportunities and also allows preservation of personal choice.
It's a far cry from a TT game though, where everyone can say what they want to say during a conversation, rather than just 1 option randomly decided. Which is more possible because TT games don't shove in random inspiration/morality outcomes into dialogue options (Since there are no options. People just make up what they want to say and then the DM roleplays the NPC's response)
If their future games feature multiplayer, having a SWtoR style system could make sense to include. That is unless they can come up with something that works better (Such as a way to actually incorporate everyone's dialogue options)
