Being Stunned is not readable for beginner PVM

Is there something to activate? Is there an overlay?

I really struggle to notice when i am stunned and i break it way to late or leave it without using Freedom. The audible cues kinda get blended out by other sounds and there is barely a visual cue, if there even is?

It often just feels like my skills didnt register when pressed. Would love for the screen to change color, or a timer with icon popping ap as a seperate ui element that indicated to press freedom, or maybe stronger VFX directly on the character?
