I dont think that many player really start type /kill during fight.. or has it binded to annoy others.. I example type /kill when see I play totally useless class with no help.. Or if gaming changes totally in other area of map and I m alone.. I dont type it on fight.. But I like to say disabling it makes only people start do grenade suicides more.. Because sometimes just have to type it.. But I dont mean that in middle of fight..
