Sadly I think that due to Blizzard's big shift to "Class, not spec" they pivoted to in Shadowlands, we will not see as much spec balancing this expansion as we should. I might be proven wrong as time goes by, but given the hilarious disparity between the best and worst of most multi-dps specs (Unholy/Frost, Affliction/Destro come to mind as the worst offenders), I think it's a safe if irksome assumption to make.
