OP is right: obtaining Wheeling Thrust at 58 breaks the expectation that you're getting stronger/learning new techniques/attuning with your job crystal soul. When you, the player, realize that the game just made your skill usage more complex but not more powerful, you feel slighted by the game and whoever designed the skill/quest.

Having both skills is manageable, or even fun to learn and execute, but the experience of receiving Wheeling Thrust at 58 is absolutely a punishing one for the player, as it's out of line with every other skill learned by not making you stronger.
