I'm using arrow keys remapped to WASD and grid layout, I also have the W key on E (for STOP) and the E key on Q (for attack ground). all the other keys lost I don't feel pressed often enough to need remapping. I also have attack ground on mousewheel click.
But being actually knowledgeable about the game and therefore one the best suited to balancing a new faction should count. I guess in Relic's eyes it doesn't?
