If we look at it from a normal pov, I would rather say Uttaran is more of a Tapasya's story rather than Ichcha! Tapasya bought Ichcha to her house, Tapasya married Veer wrongly, Tapasya wanted to kill Ichcha, Tapasya made Ichcha get married to Vansh, Tapasya was responsible for Vansh hating Ichcha, Tapasya met Rathore, Tapasya got pregnant, Tapasya plotted ways against Satya and Saanchi, Tapasya was thrown out of B house, Tapasya started a new life with Rathore, etc etc...its more of a Tapasya's begining moves which eventually led Ichcha to react to all those moves...and since Ichcha is portrayed as positive, obviously she is a lead! But u've gotto agree that without Tapasya's moves, the story wouldn't have been possible! Which obviously means she's an extremely important character too...and a lead! And now, she's portrayed as positive too! I dont why many people tell that she 's not a lead...she is infact, a lead! This story has been more of Tapasya's way of living life...and only Ichcha's way of reacting to Tapasya's moves..and this a story of two friends...and the two of them have equal importance!
