Infinite Boomerang Spam

[Remmon]

In other words: If you've gotten cuffed to a chair by an antagonist and there's no one in the vicinity to save you, you're dead no matter what they're using.

Except that to kill someone with a boomerang in this way is the work of mere seconds, any other way requires either extensive preparation or a good deal more time, giving people nearby a chance to react and do something about it. Adding a short cooldown or even just stopping the boomerang from being thrown in melee range would put the boomerang back in line with other syndicate weapons.
