Like it or not the simpler BG2 style of romances x friendships works so much better. Simple and elegant.
Err, much as I like the Jaheira romance in BG2, it's hardly simple! I certainly never managed it without a guide, anyway. And when I first played I found Anomen as the only male romance option hugely disappointing. BG3 romances and companion relationships aren't perfect, but if Larian had had no more ambition than to try to do what had been done in BG2 that for me would have been so, so much worse.
