I guess my point is that the rulings of crews per pax haven't changed on the aircraft,
from a safety perspective. Service levels are an altogether different matter. I remember being in AN first class on a MEL-CBR sector at dinner time. The crew worked liked cut cats to get the full meal & bar service done in time. I was actually a bit tardy & the CM came up to me & said;
"It's not MEL-SIN you know!" 
My only point being, that under the law, they cannot go below a certain standard, however, from a service standpoint there is no definative number of crew per level of service. In which case, you have a contentious point with your company.
Anyway, fight the good fight &, at the very least, do it for the staff that are about to be shafted again!!
BOHICA!!!!
