Gajra may have failed with Kunal and Nandini but how does that mean she did it to glorify Mauli? Mauli IS the victim! She's the one who got cheated on by her husband and her best friend. That doesn't meant it's glorficiafion of Mauli's character, it's just how it is when the third person is cheated on. Her character is such that glorification attempts aren't even needed. You feel for her because she's always been a good person.
Exactly, Mauli's screenspace is the lowest. She basically was there for many episodes to push KuNan together, at point I was so irritated with her using same dialogues in every scene. It's obvious Nandini wasn't meant to be a grey character so the whole whitewashing process of Nandini has actually ruined the whole show including her character. There's no need to glorify Mauli, people would have sympathized with her no matter what, she was cheated on by her husband and best friend. Even now Mauli's scenes that we see in OLV are not included in the show, she rarely has solo scenes, the only time show was Mauli centric was during revelation and even then the dialogues were taken from SM, how can they go wrong with a character who's loved by the audience?
It doesn't hurt that Aditi is an amazing actress, she makes Mauli real
