I'm not happy. First we lost Shyvana's human mother, instead her egg was tampered with by a mage and that mutated her. Yvva wanted to kill Shyvana and her father wanted to raise Shyvana. Now we got this kidnapper who doesn't have a name, who I don't care about, who dies. Where is Shyvana's father? Where is the time Shyvana's father was killed by her mother? Where is the time she spent trading game in a Demacian town? This is a straight up emotional investment downgrade.
They removed the explanation behind Shyvana being a half-dragon. We went from human parent and dragon parent to a mage tampering with her egg to make her a mutant, and THEN to no explanation at all. She was just kidnapped. Screw that guy. He's just a kidnapper.
Yvva. What is up with Yvva? She LOST her motivation. First she goes after the stolen egg. Later she feels Shyvana is still out there and goes looking for her. At this point, presumably because she wants her child back. She goes and burns down anything between her and her daughter. I can understand the ire. She burns and kills Shyvana's kidnapper, understandably so. Yvva isn't trying to kill Shyvana for being a mutant here. As far as can be seen, she just wants her daughter back so she can be raised properly, like her other children that left the nest.
The scene of the battle between Jarvan, Shyvana, and the Demacians has been downsized. What happened to the petricite building and petricite arrows that helped ground Yvva so Shyvana could fight her? What about the burning power of the fire rune in Shyvana that she dug deep into to draw out power from so she could RIP Yvva's heart out?
This was a change for the sake of change that decreased investment in the character and removed side characters that helped with investing the audience. The narrative presented here? I would say I just didn't care about it, but it is worse, because I know there is a better version of this story. I am disappointed. I expect better because it WAS better.
