CRPG romance has been off-putting and kind of downright pathetic since basically forever. Seeing friendships and even romances develop between characters that are not your own would be waaay better IMO, and it'd more similar to watching characters develop like you would with a movie or TV show. I think player-to-character friendships can feel more organic, because it's usually less characters being boiled down to "you click da right buttons in order to unzip their pants" vs. "you did not click da right buttons to unzip their pants" and more "hey, the player is actually taking the time to talk to and seemingly care about the characters around them". Maybe I'm wrong and it's just rose-tinted glasses to think that, e.g., the PST party characters feel way more cohesive/grounded and less artificial in how they're presented and developed over the course of the game, I don't know. But I do know that seeing characters rubberband up and down with their "I LOVE/HATE YOU" meters as a result of usually minute decisions about (what are supposed to feel like) spontaneous situations and conversations seems farcical. That sort of thing should really be reserved for decisions with major value implications (...maybe like, um, violently stomping squirrels to death or tossing bards off cliffs for no reason, both of which everyone in your group just gives a thumbs up to and blissfully ignores), as I just don't think that's how these things usually work out in reality. Though actually unresolvable incompatibilities between characters should probably lead to conflict, and yet they inexplicably hardly ever do in these types of games as well! It's a "you can have your cake and eat it too" situation, except the cake tastes kind of bad.
Never mind that only characters mirroring one another liking and/or falling in love with each other is super boring. Most works of fiction with an ensemble team of characters are about people with all sorts of different backgrounds, beliefs, ambitions, values et al. growing to respect and like each other as they learn to appreciate those different qualities, particularly as those qualities come to use in a variety of ways in different kinds of situations. Imagine if Star Trek was just 10 of the same characters running around agreeing with each other: it'd be absolutely terrible.
If Lae'zel and Shadowheart magically grow to respect and/or outright fall in love (uh...well, maybe not) with one another by the end of Baldur's Gate 3 instead of keeping on with same old same old, I will happily eat at least some of my words here.
