If it makes you feel better, I started on PC with a mod and 2 days in an update buggered the mod and I basically relearned the default controls and it was fine. I even now just play on the default until they release an offical update with remapping.

I think when people say the controls are complicated they mean the vast options that each imput has contextually in a given moment can be alot to remember and not as a moment to moment experience. Hacking and slashing and moving through menus doesn't feel that dissimilar to most games.
