Fortunately we’re all different and many of us, like me, enjoy what we’ve seen of the BG3 companions to varying degrees (and I always prefer the pre-made companions in other cRPGs too). Others are okay with some but can’t stand others. And some folk, like you, can’t stand any of them.
There is a workaround in EA that lets you create a custom party, though it’s a faff and quite resource heavy during character creation. If you’re not aware of it, though, and want to try I’m sure I can dig out a link.
We’re expecting there to be a more official in game option for custom parties in the full release in August, though it’s not clear whether there’ll be the option to create a four person party from the start like the EA workaround, or just to “hire” custom characters as per the twitter link someone shared in
another post where you brought up the same point.
