crouching and phantom are, yes. ads is very much not helpful (the burst mode for the bulldog goes really far up, and the vandal ads spray goes everywhere). i think the ads spray will go sideways (and farther up) much faster than the normal spray (i might be wrong, but ive tried ads spraying before and it went wild. so yes, ads spraying goes everywhere and is practically uncontrollable. you would be much better off just crouch spraying w/o adsing.
all im gonna say about the hypotheticals is that the line “am i doing something wrong” doesnt sound particularly theoretical, but if it is then ig it makes sense
