I came across this thread that compares the current Smuggler Pistol Whip (which is classified by some as being OP'd) with the new upgraded Spy Flashbang. Both Flashbang and Pistol Whip do the same 'knockdown' effect of removing their opponents' ability to attack.
Of course, it's unlikely it will make it to launch like this. (The original duration of Pistol Whip was six seconds, but reduced to four.)
