Flashlights are still switched on and off, besides I think CT's could use flashlights so rule stays as that is relevant most of the time when it is off we have had this as a problem. Better as it is or when we have flashlighs for some reason back, someone would turn around and say, hey thats not in rules ...
about second one, no, they don't need to know, CT's must give FD. Non wants that the guys are crying for FD etc. Better that they learn the good old way. CT's are responsible for giving FD's or they get punished eventually for not doing it.
am about third one, since when do we play like that? We check vents even if the guy is not in there. So this won't be changed to a new rule. sorry but I keep all how we have played more or less and there's nothing new.
