Look, while I don't like the idea due to my ideals of combat, I think it should be done unless you disable TFA hitmarkers entirely.
My guess of what should be done is probably in house code, or maybe get some addon that shows all hits as hitmarkers. Could solve melee stuff, probably?
I am more open to question that mechanic and its fitment into the server, rather than implementing it. If nothing is done, I believe it is unfair on S2K for vorts, don't get me wrong.
