I forgot 99% of the players on here don't play ZIlean.
You can literally dodge his bombs without even noticing he was aiming at you.
The bombs don't stun or detonate when you stack them on the ground.
The bombs don't prioritize the target you hit with the first one.
The bombs don't detonate if someone has a bomb on them, and runs into another one (no stun)
A zilean that plays backline and is "completely" safe, tends to be not where he's supposed to be
- slowing players and peeling
Then we take a look at Morgana the 0 effort mage that is "too safe" to play against.
-stuns roots and does more damage.
-offers more utility than Zilean does
-can wave clear with half the mana Zilean uses
Meanwhile Morgana can literally top, mid, bot, support
While ZIlean is stuck pure support with 0 control over whether he wins or loses the game.
But the Morgana Lux Neekos Brands can randomly ult and kill half your team.
Hell even the Morgana bind hit-box is bigger than Zils bomb, with absolutely no-skill required to play.
A Zil one-trick will take 2x the effort to play, while the Morg takes half as much and just blindly throws binds and people die.
Zil is not good early game
Zil is not good late game either, when people dark harvest reset through all of your resurrections and camp the idiot you revived because they flash away anyways.
I can play morgana, tank all of your hits and 100-0 your ADC with no effort.
Zil just gets laughed at 3 shotted and body camped.
