You're not mentioning a lot pertaining to these traits.
She has a slow, but it's tied to a wind-up skillshot that requires her to his enemies with the edge.
She has a stun, but she needs to set it up perfectly off of a wall jump.
She has %hp damage, but who doesn't At least you can build to counter it, unlike some people 
She has a great gap closer/escape, but it has a long cooldown and, if she uses it, she won't have it again for a while.
She has true damage, but it's partial and greatly drawn out. You can easily predict when it comes.
She has a multi-purpose ult. So do a lot of champs.
She has a shield, but it requires her to AA, and the shield doesn't block one type of damage (And doesn't block true damage at all, iirc)
She has a heal, but it's tied to the same criteria as the slow above.
