How make the Devs killers?

ShyN3ko

Sry for my bad english.
If you find bad english, you can keep it

Informations:
The Devs said in 1 livestream(dont know which one.Have someone a link?):
"Killer shouldnt be strong or viable.
It should be fun for both sides."
Btw i hate this.
This is bullshit for balance in video games.
But after this livestream, they release "the spirit".
A high/mid tier killer.
So i dont know, why they said killer should be weak, but fun to play.
And then they release a good killer.

DbD now:

They released Legion.

He/She need no skill to play.
He/She is unfun for both sides(For the most people).
He/She is weak.
He/She is strong.
He/She has only ~14 viable perks.
He/She is rly strong with weak perks(Dying Light,Thanaphobia).

How did they create this?

PS:

Dont show use gameplay videos,Devs.
Your team cant play this game.
And it just hurt in the eyes.
