I think a Shyvana Rework is in order.

Shyvana is... boring. She has the potential to be really cool, only it's wasted because she goes from a fast moving auto attacker while a human to a fast moving autoattacker with some aoe as a dragon. Wouldn't it be cool if she got different abilities entirley when she became a dragon. I think she should also become HUGE, like, 30% bigger than her current model, and that means her ult width would also be 30% bigger. She should really feel like a dragon when she transforms, dragons don't run super fast and punch you, they breathe fire, they eat you, they stomp on you. Here are my ideas, I don't have actual numbers though...

Shyvana's human form can stay the same, it makes sense for the most part. Her Dragon form, should yes be 30% bigger, and as for abilities, her Q I think should be the same idea, of a bite, but be more impactful as well. Have it apply a decaying slow or damage over time. Her W should change in dragon form. Dragons aern't really super fast runners (so I'd imagine) and usually just use their wings. When Shyvana transforms her W ability should become an ability similar to what the Dragon objective does when you first attack it. She releases a gust of wind knocking people away. BUT if her W was changed in dragon form, she'd lose the aoe on her burnout and end up dealing LESS damage. That's where her E comes in, her E now breathes fire similar to Rumble's flamethrower except it is a toggle. The longer you have the toggle on, the faster Shyvana's fury drains.

These are just some ideas that I had thought of right now, you don't have to agree, if you don't agree say your ideas on how Shyvana should be reworked.
