It's not an issue of equal attention, if you had bothered to read what I had said. It's an issue of spending more time on something you have less experience doing.
I read what you said and I disagreed. It isn't just a matter of knowing how to do mouse and keyboard controls. It's a problem of designing a game completely around gamepad controls. If you'd read what I said, you would have realized this. Porting a console shooter to the PC is easy. However, if gamepads are the focus, then M/KB will not be used to their greatest potential. For example, this whole automated traversal mechanic is very likely the result of the gamepad focus. Anyone who's played a PC shooter like Quake knows that moving around the environment, jumping across gaps, moving to cover, etc, is really easy. It's far less easy to do with the lack of precision offered by analog sticks. This isn't that hard to follow.
