You're literally just listing aspects of her abilities without really saying why it makes her overloaded. Simply having true damage on an ability or having spell vamp doesn't make a champ overloaded.

You describing one of the most simple braindead champs in the game:
>woooah nasus is so overloaded dude his passive gives him lifesteal and he has an infinitely stacking mechanic and his ult gives him armor health AND magic resist?!? wtf he can remove enemy armor and mr in a huge zone too what da fuuuuuck

I think you have a very different idea of what overloaded means.
