I do think fast travel (and long rest) needs a major redesign in BG3 just because it makes a lot of other things redundant [...] but I don't currently have thoughts on alternatives.
Which I don't see as a big issue.
I think the most valuable thing we can do, as players giving feedback on an early version of the game, is tell Larian what doesn't work, and why it doesn't work. Whereas how a given subsystem should be designed really comes as a distant third.
If we managed to convince Larian that a currently-poor subsystem really needs to be substantially revised, that would already be amazing. (Yeah, this last idea could be nuanced and discussed a lot. But I'll keep this post short.)
