Characters that make other characters useless are unhealthy. Not Sejuani or Maokai.

is a prime example of this.

I am not talking about or flash ulty, what I am talking about is these characters make your character useless in its entirety. At least in order for Malz to make you useless, he has to waste a sum spell and puts himself in a prime spot to me focused.

Characters like who can poke from afar, shield others, and stun you while increasing their own movement speed can make it so "No matter who you go in on, all of your damage is changed to nothing."

A can't be faced when you are playing

Another example could be or (This is rare tho)

At least when makes you useless, it's literally her entire job (This isn't healthy, but it isn't as bad)
