The one and sole reason: the combat. Its too damn random, sluggish, and laggy. An enemy will be a cake walk one time and the next he's throwing perfect counterattacks everytime while I'm pressing A to parry with the game not responding.
*** bullshit.
And don't tell me I don't like a challenge and that I'm some lazy gamer who gives up on difficult games. I enjoy a very hard game; but a very hard game that has fluid combat and consistent enemy difficulty and AI. Randomness just equals frustration, not harder difficulty.
