It's pretty absurd that reinforcements *don't* count. I have no idea why they changed it.
My two theories are that it was either to save a little space on the page, or a shamefully hamfisted attempt to solve the "games with large gangs take too long" complaint.
I don't like the rule either, but I think their intention was to slow down big size crew in campain. But, in my opinion, this rules stop some tactics to be executed. Like cheap canon folder.
