Can this game be beaten with minimal/no swordplay?

I know there's a lot of complaints about the combat system, and the general response is to practice. I have done a fair amount with Bernard and my sword skill is something like 11 or 12.

But I'm on PC using a mouse, and I find it really frustrating to perform any kind of combos, let alone any kind of pre-meditated move because even the slightest movements of the mouse move the combat cursor all over the compass. In combat, I'm trying to strafe while continuing to get a fix on the enemy, which is very hard to balance with sword position.

But hey, I abso-fucking-lutely love this game, and want to keep going, so I've worked around a lot of ordinary combat situations, and have actually gotten past >!Pribyslavitz!< using mostly stealth, bow, and speech/charisma.

It's honestly been a lot of fun playing that way, but, with minimal spoilers, how likely is this to be a long term road to success?
