Latency issue in this game...

[Altena]

I'm talking about the completely avoidable (with proper coding) issue of skill effects (like hallowed ground or benediction) applying but still getting killed. Silence going off on Chimera but Ram's Voice still going off while Chimera was under the silence effect, and things like that when no other signs of lag are present in the game.

This is a design choice, that SE have gone over multiple times - and while I don't agree with it, it's here to stay unfortunately.

All skills, both on and off GCD skills, are applied after the animation (or at least a certain point), and are not applied the moment you hit the button.
This is a design choice from SE's perspective.
