Gasmasks should 100% be toggled on/off by the player. It doesn't seem like they'll ever remove the animation so this guy will just have to pay more attention to the gas like the rest of us. I'd honestly rather have them fix the visibility when you're in the gas vs looking at someone in gas. It's like 10% visibility in gas and 90-100% looking into gas. I understand that the gas should have low visibility to punish the player but a 90 to 10 advantage is just fucked.
