Ahelp it and get 'ic issue' as a response? Having to further clamp down on potentially bad antag play just for a shit mechanic to cover potentially bad non-antag play doesn't sound particularly appealing. Having played with this mechanic, it (in other incarnations) often procs on any brute damage, making it far more annoying than you might expect in regards to breaches and the like. As well as, most notably, when you want to say something to the person attacking you.
