Role-based Profile Mapping

So I was wondering why there’s a beta on production servers, and in conjunction with how messed up SR is across the board, I had a thought. I don’t think the dev team had adequate data to reliably build role-based profile based on legacy data due to role swapping and the general volatility of games. So they release this “beta” on production as an information net to build the majority of active players’ role-based profile for more accurate placing come Season 18 (or whatever we’re on now). If that’s the case, a lot of the chaos and complaints in the beta will be resolved, assuming the aforementioned profiles were built with any reliability.

Am I a wishful thinker? Thoughts?
