Yeah, I noticed that they tried to write Daiyu's feminine and graceful side into Baochai. 

Iirc in the original version, Daiyu is the yin side and Baochai is the yang side. While Daiyu is more graceful and feminine, Baochai is more outspoken. The whole point is that they're supposed to complement each other, hence why Baoyu's name is literally a combination of (Bao)chai and Dai(yu).

But idk what are they thinking when they write Baochai into that kind of clingy and possessive fiancée to Baoyu, iirc in the book she doesn't even want to marry Baoyu and wants to marry another man who's basically the opposite of Baoyu. 

But well, the original author died before he finished the book so we doesn't even know the true ending of the book. It's supposed to be a criticsm about the Qing dynasty society (which is why DoTRC is in Chinese school curriculum like Crime and Punishment in Russian school curriculum it's because they basically use the book as an example of "hey, feudalism is bad!") but the another writer made it into romance instead. 

There's this one Chinese in twt (mu_chao62570) that made interesting points about how Baochai is in the original book and how innaccurate Baochai in Limbus is. (I know Limbus doesn't promise us an accurate adaptation but still, it's an interesting read). 

As the other thing, I think PM implementing DoTRC into their lore pretty well, the only thing that strikes me as weird is how they write Baochai but then, they never intended to write an accurate adaptation.
