The circle-strafing isn't actually a problem with pointer controls, since your reticule will be at a specific point on the screen according to your turning radius; you're just keeping your target off-center from the screen. This isn't any harder than circle-strafing with two sticks, once you know how. And, hell, you're more accurate when you do it.
Yes yes KB&M is better, yes, I acknowledge that
There's just no real respect in which dual analog trumps pointer controls
