I'm not throwing shade at BG3; I've also enjoyed it, but something about the sheer amount of options and more widely diverging story paths in Wrath just does it more for me. I also like the art style more, but that's strictly subjective and I accept that.
To a lesser and more personal extent, I despise Wizards of the Coast/Hasbro and their recurring attempts to monopolize and bully third party game developers and players alike and I don't like to even indirectly trickle money their way compared to Paizo. Yes yes, no ethical consumption and all that, but Paizo's way less fucked up with both distributing game materials and open licensing agreements.

That's all I had to say. If you've already finished BG3 or it wasn't quite to your liking and you'd like an alternative, give Wrath a try. 
This is just a theory, but does it have anything to do with the order the party is in on the hud? It may be random or based on relationship though.
yeah i'm not too sure, plausible bc ive done a few of her quests, but shadowheart and gale and i also have pretty high relationship and they dont talk too much so i'm not too sure
