For me so far, Rohit’s acting/his expressions have been very restrained towards Abhira and others too. Not just towards Ruhi whereas Sheh as Armaan was very expressive in his expressions towards everyone including Ruhi. I feel like it’s not the same Armaan and Ruhi anymore because both characters have been changed a lot. Ruhi was never this extrovert. Prat’s Ruhi was quiet, introvert and depressed whereas this Ruhi is more outspoken, social and doesn’t seem depressed. Previous Ruhi used to come across depressed and heartbroken, but this Ruhi comes across as a child who’s upset her toy or chocolate has been taken from her. This Armaan also doesn’t seem guilt ridden and emotional all the time like previous Armaan was. This Armaan is more confident and all. Both of their characters have been changed and even though the names are same, but it feels like two new characters have entered Poddar’s house. I can’t blame Rohit for this as he’s very expressive too. He was very expressive in Razia Sultan and from what I can see in Dhakhan too, but here not sure if the makers want him to act this way or his acting has suddenly changed.
Yeah, one of the factors for the change maybe a shift in writing, no doubt. But I think one can't discount the acting as well. For instance, some of the scenes where Ruhi was coming onto Armaan (the one on the stairs before Abhira's accident comes to mind) the expressions by Sheh used to convey a mix of ardent pining/angst/guilt/tears (rinse+repeat). But Armaan 2.0's expressions don't convey the same emotional vulnerability vis à vis Ruhi anymore. He no longer seems that moved by her words, which is a drastic shift and now we see more of an annoyed/dismissive attitude towards her. She no longer seems to get to him in the same way fwiw.
Even in scenes with Dadisa, when she showed her disapproval/anger, Armaan 1.0 used to give these intense crestfallen/despondent/teary-eyed looks, whereas the current Armaan comes across as more stoic and unflappable.
