I never really understood how ESDF was in anyway better than WASD, with the exception of wow, you don't need more keys than WASD can reach and WoW hotkeys are cirvemvented by CTRL/Shift, certainly not in FPS, RTS have a few more buttons to push, but you don't need to be moving anyone or stretching your keyboard hand for those. Even the "natural position for typing" isn't really a strong point as I never have any issues reaching any keys, and the true position a typist learns is ASDF.
The idea of ESDF is that you unlock more keys to use, and thus become more flexible. Suddenly the T, G and V keys become more accessible, while the W and A keys can me mapped to different functions and, if you find it comfortable enough/have long fingers, Q, X, C, Y, H, and B keys can also be readily used, all while shift remains easily available as well. Basically, you are more flexible in how to arrange your own custom key bindings. That's the idea anyway. I've also heard it's more comfortable for people who can professionally type, though I couldn't verify that.
Sure, FPS might not benefit, but I've played several RPGs where I wished I had just a couple of extra keys that were easy to reach.
