PS4 and mouse (and keyboard)

Hi, i've just switched from ps3 to ps4 a i was eager to try out mouse and keyboard, however i encountered some issues:

1-am i missing something obvious or is it impossible to set the cursor speed?

2-as far as movement and camera go, i set the "legacy mode", because the normal mode felt horrible, that said, is there anything more "optimal" for movemente than the usual WASD? i was hoping for something like Diablo 3, where you click and move...

Thanks

I went through 3 mouses until I found one that let me move the cursor faster. It was a generic dell mouse. My trackball mouse moved the pointer about 3 inches on screen It drove me nuts.

I tried changing the mouse sensitivity settings for the controller, in hopes it did something, but Im not sure you can do anything about it.
