...Sorry guys, have to point this out. (Ekko)
Ekko's: Passive: Vel'koz passive with proc on autos, slow, and ms. Q: Orianna's q-w-e, with a higher slow, but without the shield. W: Eve ult, with delay, added stun, and high shield regardless of champs hit. (Also built-in Zed passive without the cooldown) E: Standard dash with the second part of Elise Rappel. R: Essentially an instantaneous Ziggs and Zed ult (at least the shadow and invulnerability) combined + summoner heal.
It's like Riot wanted a redo on all the champs they felt they could do better with. Ekko has a ton of counterplay, and stupid mana issues I know, but all that aside...this is the definition of overloaded.
