DmC is also more lenient with a ton of things by design, so you don't really need to use any of its mechanics very optimally to complete the game. Stuff like Osiris being able to pick up everything below you, how much of Aquila is automated, the grapples, all the AOE moves, the amount of i-frames on dodges, being able to parry just about everything, etc. If you were to play DMC3 with DmC controls it would feel incredibly awful, just like if you had DMC3 controls with the DmC moveset the game would be pretty easy.
It might just be a design issue instead of a control issue.
