Every single FPS game there is has flash grenades. They are almost always made to blind people even though it is not grounded in reality. In many of these games it doesn't matter since they are not really realistic but Insurgency is.
I don't like how the flash bangs can blind people from tens of meters away. No grenade that small can create that much light. In Sandstorm there is a lot of room clearing so why cannot the flash bang work like in real life. In a perfect world with the perfect Insurgency the effective radius would be small in an open place and cover a whole room indoors. The effect would not be blinding but cause your character to panic like when suppressed and make your vision shaky and unclear.
I don't know if this is possible to code with a reasonable amount of time but I would like to see the flash bang implemented correctly in a video game for once. I am sorry if my word order is sometimes irrational. I don't speak English as my first language but I hope I brought my message across.
