I don't see how replacing Marine would help with that, but if you say so.
There was a bit more to it than just coomer pandering. They had fun with it in an entertaining way, especially Marine and Towa. Then there was Noel being a total dork. Lamy also got creative with her throws. I thought it was fine, other than the MV which was just weird.
EDIT:
I mean they replaced Marine with this for like 2 seconds before changer her back.
