1. The game does have less combat depth. Less combo/moves, color coded enemies, and the lack of style change make it extremely low in comparison to lets say DMC4 or DMC3. -The skill ceiling in DmC is also considerably low.
2. The game IS too easy. All you need at most is 1-2 items per level and even the most casual player can easily do DMD. Not only that, Devil Trigger is pretty much auto win, making HaH a joke.
The tactics needed for completion of DmC's DMD mode are almost exactly the same as GoW3 or such likeness.
Honestly I find this game easier than Darksiders 2, except for that game has a lock-on.
