KN always the strongest villain ever show has so far.
But they always gave him lot of breaks in between and finally killed him off.
If i'm not wrong he was there for 3 or 4 months after 10 year leap and on a break and coming back after 3 or 4 months later.
And i think only in that phase till the end of Sooraj's banduva phase,KN was in his all glory.
After that track,they made him mad and again focus coming to him for a shorter period.
But by that time,Imli turned villain and RV enters and after that KN sidelined a lot.
And after that they killed him off and take 5 year leap.
The build up and time and energy they are giving on Imli continously for months now.
I don't think KN never got that and i think he deserved more than that but sadly cvs didn't understand it.
Before 10 year leap story may be different,i don't know that and the creative team might have different team that time.
