Will KS decrease in TRPs?

Some of our favorite characters have left the show (Prachi, Roshni...) and now it's been speculated that Arunima Sharma also is leaving the show. After Prachi's exit, Gurdeep did a good job and she's currently doing it. But somehow we all miss Roshni, our ex-Pia. Now, as we heard that Arunima is leaving the show....so...I mean will the TRPs decrease due to this???
