If someone wants to test SMN's abilities with B4B and other actions, they need only gear their ACN the exact same way as the SMN down to Allagan gear so it's even, use all the abilities it has access to then like Internal Release and so on, plus Aero, then factor in the stat differences that a SMN would have and see what the result is. I'm sure this wouldn't be very hard to do with someone that knows how to do it, I myself don't, but ACN can do all of the things if you've leveled it that would make SMN having them broken as hell.
