It would be way easier to pick the direction of my strike if I could simply move the camera normally. Sure, with unrestricted motion I might end up looking a bit far to the left/right of the enemy when choosing to hit him from that side, but as long as he’s on my screen, that shouldn’t be any sort of problem.
The relationship between my limited mouse movement and the feedback I get from the “crosshair” feels very iffy and difficult. Doing away with the constraints would make direction easier to choose, provide much more control, and feel way more natural.
