Has anyone taken their time to read Senna's abilities?

Why does she have like 4 champions' passives shoved in there:

-J4 %current HP damage(scales to 16% as well) -Sort of an anti-Thresh passive, you can't gain AD by level up, you can stack it -Sivir movement speed(which actually is based off opponent MS, which is adaptable to even a Jhin running at you 600 MS) -Kindred passive, it not only scales really hard, but gives lifesteal as well past the cap, if I understood in correctly

And some on-hit damage as well.

Her Q has a heal, her W root is very long and her E MS is pretty busted cuz it's teamwide.

Plus her ULT it's something else, granted it's on a 160secs CD. Blitz base damage, takes up literally whole screen(about as hard to land as a Karthus ULT lol and it's teamwide shield).

It may not be busted in practice as it's on paper since she lacks the raw DPS of other champs(slow attacks, less damage on crits), but darn have Riot worked a lot to create another way overloaded champ.
