I don't know if you can make some sort of designation or animation for the enemy when they are blinded.
I am constantly faced with the fact that here in the room exploded a light grenade, I see the hitmarker, I go in, and I get hit, as if the light grenade and was not.
With animation at least it would be clear whether the grenade hit the enemy or not.
Example of animation: the character covers his eyes with his hand.
This is just a visual effect. The position of the weapon does not change, as, for example, when climbing over an obstacle.
In addition, it would be nice if the animation of throwing a light grenade and returning the weapon to your hands was a little faster. Because it should be a quick action "Throw - attack", aggression
