I feel Shyvana is in the wrong catagory of champions.
Riot lists her as a Juggernaut, like Darius, Garen and Illaoi. But functionally, she is much more like Udyr, Yi, Trynd and Kayle.
She is a high DPS champion, who benefits a lot from attack speed, primarily uses basic attacks, has good chase and running power, a lot of movement speed, mild damage mitigation and otherwise a kit aimed completely at doing as much damage in a DPS format as possible. This is what Yi, Udyr, Trynd and Kayle do. They build attack speed, on hit/crit, a couple tank items, they have a manner of defense in their kit(Q dodging and heal for Yi, Heal and Ult for Trynd, Heal and Ult for Kayle, Shield and Lifesteal for Udyr) they all only have a single CC in their kit that isn't very strong when compared to tanks.
On the other hand, people like Darius, Garen and Illaoi primarily use abilities to deal a large burst or short window amount of damage to targets, build very tanky, almost fully tanky, don't care about attack speed much, each have some solid CC, don't have much movement speed comparably and all build Black Cleaver every game.
Seems to me, like she should be listed like Yi, Udyr, Trynd and Kayle, not like Garen, Darius and Illaoi.
EDIT: Because most of the Juggernauts appear to be AD casters(damage is primarily through abilities) while Shyvana is more like a DPS(Abilities augment basic attack DPS, benefits from attack speed).
(group a) are the first type and what most people think of when they hear juggernaut the other being champ who are more auto attack reliant are
(group B). Group A has better team fight potential while group B has better sticking power and dps.
they have ways to avoid damage whether it be alpha strike, meditate, intervention or undying rage. It allow them to be deceptively tanky with out building tank. Group B juggernaunt doen't have anything like that. Also they have more "mobility" then group B
is if you through fervor of battle on top of those. Or if the other team is stacking lots of MR relative to armor.
