I think what he means is that he cannot re-bind the keys. At least, that's the way I interpreted it.
Since this came out on consoles ~ 2 months before it hit the PC, I imagine it plays pretty well with a controller, though.
I plan on using mouse + keyboard myself, but I hardly ever re-bind keys. I learned a long time ago that it's better just to get used to the defaults that everyone uses rather than fighting every single game that comes out.
OP has apparently not learned this particular road to happiness yet.
