I remember kaira fans saying that randeep should be replaced with shivin in bv2.i still feel that ashi's condition is better.bcz though the old fans of the show bashed her, she got a new set of fans which shagun did not have.even ashi said that as time passed when a group of people loved her she forgot her pain of getting bashed.but shagun didn't..
You are right.when the lovable character suhani was killed for a new FL,she was hated more.its like when soumya was turned negative for bhavya,there were many who hated bhavya for this.
I know about one show subhanallah.which were the other shows where she replaced the dead FL?even mansi faced this issue in 2 of her shows.
We can't compare whose condition is worse. Ashi was suffering mentally. Don't know about Randeep being bashed by Kaira fans. Even if he was bashed I am very sure they would not have gone as low as those trollers saying dirty things to Ashi and Sid including their family and even Abhishek's rumoured girlfriend Vaishnavi and after Randeep got BV2 they started abusing him and Shivangi along with their families. I once showed an instagram profile of one of the trollers which I think is now removed by instagram for disgusting posts.
Coming to Shagun, the problem is she was part of a continuity show. If she had replaced Ragini as Suhana then issue may not be that bad but here she replaced that character only. Tunisha gone through this issue in 3 shows where she replaced dead FLs though in one of the shows the dead FL was back.
