[2020] Fix the ♥♥♥♥ing Flashbangs please

Originally posted by Roenie: Realistic tactical SWAT missions aren't fun, they're nasty. That's why only the big boys do it IRL. If the flashbangs in Siege were realistic, they might as well give you a "delete enemy" keybind because it's the same thing. They should still be improved, they are pretty useless right now.

Thank you for the feedback!

How would you want to see flashbangs tweaked in the future?
