Moeen has delivered in back to back matches which is a really good sign for CSK and I do agree with @SaiSrini that Moeen needs the open along with Uthappa. Both of them would actually take advantage of the Powerplay, an area where they haven't done well since the last edition.
I was disappointed with the way the CSK batsmen approached it near the end of their run-chase. I would consider that as brainless batting and absolutely unnecessary effort to force the finish to a match where they clearly dominated.
I felt one thing that worked against CSK was the way Raina's age old short ball weakness got horribly exposed. I think the sides would definitely try the short bowling tactics against him in the coming matches.
Raina got lucky against DC that they didn't pepper him as much with the short balls. In a way, its good that Raina is not fixed to the No. 3 slot and that CSK have atleast opened themselves up to float Raina around.
I seriously feel Ruturaj is not ready and think he got lucky last year that he eased himself when the team was out of the tournament. His comments prior to IPL 2021 where he said "I am going to focus on my strengths of timing the ball and I am not a big shot hitter" should have given the indication that this guy is more an ODI type batsman. You need openers who can cut loose and take advantage of the Powerplays when field restrictions are on. Rayudu is one guy who did that beautifully in 2018. If only we didn't have a spoilt choice of openers, Rayudu could've been promoted to open.
