I have a Naga and when I was keybinding everything (moved from a laptop w/o mouse), I decided to keybind strafing to some of the buttons on the side of my mouse, as well as the 'forwards' function.
So to turn and move forwards I use the mouse, and to strafe or also move forwards I use the buttons on my mouse.
Kinda fucked I know, but since I have like my most important abilities bound to WAD (Silence, Trinket and RoS) I've kinda made it hard for me to learn how to move properly :/
