I have this issue often when many grenades and/or explosions are part of the combat zone. I lose the sight and can't see the enemy anymore but they do see me perfectly. I am not talking about smoke grenades. I talk about regular ones like Vortex/Pulse/Solar Grenades as same as the void outbreak grenades Hunters have. When they do Show their textures it can happen that I can't see the enemy aiming throught their sniper (because solar grenades can block the emitted colors of the red glare). Or I can't see the enemy altogether (Vortex/Void Grenade because of the dark tones absorbing some emitted light from armor). Arc grenades do that barely and I have very rarely an issue with them. The only major problem with them is, that we can't differ them from enemy ones sometimes. Everyone with a common sense of light physics should know that certain colors absorb certain light lengths. I see no reason in making pvp high texture graded for the cost of visibility and transparency. It is just annoying and sabotaging the gameplay.
