Modern 3D games use two sticks that your thumbs will be on 90% of the time. I fail to see your logic in your argument. On top of that, old-school (NES, SNES)controllers paced your thumbs in the same spot. It doesnt matter what they were doing, but they were symmetrical.
You need to play more games - only modern FPS has you using both thumb sticks at the same time for the majority of the time. 3D action games for example don't.
The old school controllers aren't symmetrical like the Dualshock - that's the entire point which seems to have flew over your head.
