Minthara players; "what romance?"
Personally I don't think the issue is about there not being enough romance in ACT III, the issue is romance not being done right because romances and their pacing in BG3 are just all over the place.
They do not evolve naturally as strangers > friendship > camaraderie > romance. Instead they're shallow "we're strangers, but let's bang as soon as possible m'kay?". Due to this lack of meaningful growth the pacing ends up all over the place and that's why it feels like ACT III needs more romance scenes to one-up the romance scenes from ACT II or ACT I and truly capitalize on them.
Divinity Original Sin II for example beautifully executed romance despite how little it had, because it only starts between the finale of ACT III and beginning of ACT IV. Up until that point the player slowly gets to know their companions and build up friendship with them, explore their backstories and establish a real sense of camaraderie. Which only evolves into actual romance if the player does everything right for their companions by ACT III, at which point it begins the relationship with a lovely romantic night spent together and plans of living together forever by the game's finale.
BG3 on the other hand... doesn't have any properly paced build up, it's just straight from strangers to immediate horny strangers that wanna bang. And if you don't bang them, they'll throw a fit with the most depressing puppy eyes because how dare you not bang someone you just met (looking at you Karlach, Wyll and Lae'zel. As for Astarion, I want to rip his balls off because his approach is just so awful.)
The pinnacle of any romance should've been in ACT III, but instead; Karlach's pinnacle of romance is in ACT II, Lae'zel's pinnacle is ACT II, Shadowheart's is ACT III, Minthara's pinnacle is ACT I (as a brainwashed victim that isn't even the real Minthara). There's just no proper pacing and that's why it feels like there needs to be more.
As I said in other threads about this; I felt far more invested in DOSII when it comes to romance than I am with any in BG3 because there they were paced properly to allow the sense of actual camaraderie to build up before romance ever came into the picture.
With all that said; Minthara for me is the only one who actually feels properly paced as her actual romance does not start until the very finale of ACT II, allowing the player to build a proper camaraderie with her due to survival circumstances before it actually evolves into something (which unfortunately is not much since she's entirely ignored by Larian). But overall I agree that ACT III romance does not capitalize whatsoever because the pinnacles were already reached in ACT II or ACT I.
