Well... the current control scheme is mostly balls anyway... It's nice to still keep it for the people who just have really become accustomed to it. The only thing I want, but am not very hopeful of seeing these days is getting closer to the keyboard controls from FFXI.

If I had to choose between what we have now and a more mouse centric mainstream control scheme I'd go for the mouse controls, provided they actually worked... but if I really had complete freedom to choose it would be FFXI's Full Keyboard set up.
