I am currently ranked Crystal and am getting fed up that the netcode ruins this game mode.

It turns a competitive mode into pure RNG. How you ask?
Everytime you press Guard you gotta ask yourself, "Hmm, will the netcode actually register that I pressed my defensive ability, or will it take two seconds for it to register, causing me to eat 50k dmg while inside this pretty bubble?"

When the enemy presses Guard you gotta ask, "Hmm, will the netcode register it late and allow me to kill him?"

Now I am not talking about the scenario where guard and the enemy ability clip through each other, because they were cast at the same time.
In many of my games I legit had situations where it needed two full seconds to protect me from damage.
