I click for anything right of "5". If my fingers leave WASD, I can't guarantee they'll find their way back accurately, and having to glance down to re-orient my fingers is a huge pain. Fancy gaming mice are off the table too - after 30 years of moving my mouse freestyle, I would hit the new buttons accidentally more often than not. This is why I use a controller on games like FFXIV; your hands never leave their resting position, so no given button press is a "risk" to execute. They're all equidistant.
