How would you reliably reproduce the combat system of M&B on a console controller? You wouldn't be able to, so it would get "dumbed down" to make it accessible, instead of more refined/complex. The curse of games focused on consoles but also released on PC's.
I'm not some sort of PC elitist (even though I don't own a console), it's not like people who play games on consoles are "dumber" or some shit like that, it's just the interface between game and player is much more limited when compared to a mouse+keyboard combo.
