I've played games ever since I can remember (50 yr old) From the Spectrum days onwards, I always used Q&A for up and down and O&P for left and right and the Space bar for fire. When the mouse came along later, I continued using Q&A for up and down and put my right hand on the mouse to move about and used my thumb on ALT & Spacebar for strafe left and right. I continue with this set up to this day and find it comfortable. I use my finger next to my pinkie for TAB and Caps Lock (Use etc) and W for Jump and S for duck/crouch. I find I don't need to pivot or move the base of my hand at all. Sometimes, I use WASD on a newly installed game until I can be bothered to reconfigure and it still baffles me why it is the 'gamers default' setup. Here's to no more WASD!!
