So, the industry is gonna adapt the standard of fumbling around in EA for ~3 years to then take a 90-degree turn half-a-year or so from the release date, going on a marketing rampage that is nothing like what the game was previously advertised as, quickly cutting away unfinished stuff and stitching together last-minute replacements for things that aren't quite up to snuff?...

...I mean, it's not that different from how it seems to work with the big studios nowadays as it is, safe perhaps for the aggressive promotion of the in-game sex and how it used intimacy coordinators (for what, exactly? Nothing happens in most scenes, and many don't account for your character's gender properly anyway) and how you can create whatever character you want for it all (as in, most non-mechanical choices in character creation amount to bugger all, identity and "body type" especially, because all the game does is occasionally acknowledge the former but without making it matter in any way when it comes to content or choices).

As for what can salvage BG3 in a hypothetical "director's cut" - I'd say they should...

...cut the Emperor out entirely and rewrite the plot, removing the butchered lore (the illithids, people turning at the snap of the finger, and especially everything tied to Balduran which came out of absolutely nowhere and serves NO purpose). Also allow for a proper Absolutist path to be followed instead of railroading the player down a very specific route. Restoring the old Wyll is probably too much to ask, but still - he was a far better character in EA.
