This is like complaining that a puzzle is too easy if you already know the solution. Fully understanding the mechanics of a game is bound to make it easy, unless heavy RNG or reflexes are involved. Even if there was a difficulty that required rigorous minmaxing to complete it, once you know exactly how to do it, there is no challenge in following the required steps. Luckily you can always make your own custom challenge. Like beating the game with a solo level 1 cleric using only a salami as weapon, or something like that. But don't ask for the removal of the tools that make the game doable for the "filthy casuals" who don't have the time and resources to fully learn all the obscure game mechanics.
