I don't know about you but the way I see it, the reason why there is no merged screen in combat is because you can choose what party member goes first if their turns are one after another. It only gets worse when all 4 characters are right next after another. Explain how would you solve that problem in merged screen with two controllers basically playing at the same time.
It was easy in Divinity, you wait your turn, when it comes, you control the screen. That can't be applied to Baldurs Gate 3 unless you are willing to give up on mechanic where your can chose who goes first in chained order. I personally, am not willing to give up on that. It's a great mechanic and often times it created some unexpected advantages that I couldn't have if say, my buffer was 4th and damage dealer is 1st. I could just swap it for buffer to cast buffs on my party, even if it technically goes last... It's wonderful mechanic that Divinity didn't had.
You solve how will that work with two controllers on 1 screen, and then we talk about merging. Come on it's not a rocket science... right...
It's definitely not rocket science. One player can push a button on the controller to yield so that the other player within the chain order can go first with full screen control. The other player can push a button to yield and the full screen control will be back to the other player in the chain order.
