No matter how broken something may be, people will always dismiss it with "Dodge the skillshot" or "Don't fight in the ult"
Dude if there was a skill that was a guaranteed 10 thousand percent maximum health true damage ability, but it was a mediocre slow skillshot, that DOESN'T MAKE IT BALANCED.
You can dodge that shit all you want, and yes, that will stop it from killing you, but that doesn't make it ok.
You seriously want me to believe that I shouldn't be hit by EVERY SINGLE SKILLSHOT in the game for things to be balanced? There's not a single person in the game who can avoid that and still play to max potential. That's an unrealistic expectation.
