If you implement a system or team that's dedicated to researching trends in efforts to provide information for the development team to balance the game, you can also implement a marketing gimmick, something along the lines of the game is constantly evolving and enemies adapt to players, they learn from you and "strike back harder" bla bla blah... and use that as a twist to cover your adjustments basically tweaking enemy strengths and resistance against specific play styles that you believe are against the original vision for how the battle would have gone down.
