For fifty bucks it should only take me 10min to get used to it. I can go back to playing ME3 after not playing it since Kasumi DLC and it takes me 5min to relearn and remap after I have been playing other new releases. I am just not that satisfied with it, the controls and game play should be intuitive than this.
The price of the game never ensures the time it takes to get used to the controls.. it's already said that key binding will be added in future updates.
I've played with m/k and it's playabe.. actually I played about 2 hours like that and then I tested my gamepad and I was more confortable with it. This is like complaining because playing Street Fighter 4 with a keyboard it's not the same as it is in consoles.
The game it's pretty good.. u are complaining too much and missing all the fun and pretty good boss battles and questing.
Cheers
