Being killed from off screen projectiles issue

Hi
There is a significant issue if you don’t have a screen clear meta build of being killed from off screen by enemies with projectiles or spells, what is the aggro range of these enemies as they see me long before I see them(as they are off screen and way before my character will be able to auto target) and are mass firing projectiles that kill you for example the crabs with poison projectiles in a group are devastating when you can’t even see them just their projectiles is ridiculous, they can easily kill you before you can kill them( or see them) believe that it would be fair for enemies to only fire at you when they enter the screen and not before. I would be grateful if you would investigate and rectify this as I believe you already addressed some enemies that can one shot you from off screen as an issue but for some reason didn’t include the enemies that can equally kill you in a group from off screen which is almost the same as a one shot just numerous projectiles hit you at the same time instead of one. Kindest regards
