The best part about this is that it's nothing but a cheesy excuse.
You can already get pretty accurate numbers just by putting in the effort/time and testing them. We already have a pretty good idea on what the stat weights are, accuracy caps, how certain abilities stack, etc. Anyone who has even touched an MMO before stats were common knows that these things are relatively "simple" (Take some time and some math) given that you have access to a combat log.
They're just making things harder to discuss with the players for no reason. Not like they ever discuss changes and the like with us anyway...
