Ok, so we had a misunderstanding on my last one
"so in essence ROF will decrease but not increase if change of range band, right?"
If while rolling a multiple burst you change range band and the ROF decreases, you roll less dice, as PFC said.
But if the ROF increases, you DON'T roll more dice.
Otherwise answer a) and maybe b) would have been YES.
Did I get it correct?
