Yup, don't like the stretched feeling with my pinky trying to reach Shift and Ctrl on ESDF, so balls to that. WASD for life and I don't care what anyone thinks of me! /edge [Edit: Hell, AltTab too for when I'm not playing a game! WASD truly is master of all.]
No doubt there are extra keys accessible with ESDF; but I've never played a game that'd need 'em, so there's no point. The last game I played that required more binds than WASD might seemingly offer was WoW and in that case, Ctrl/Shift/Alt did the job something handsome.
The muscle memory I'd have to overwrite is bonkers. My left hand just plops on to a keyboard with fingers on Shift, A, W, S, D and Spacebar like it's the most natural thing for me to do.
