First off you wasted $4000 I could have bought 2 High end machines that would be far better than any alienware machine for that amount.
Secondly there are a handfull of other with the same problem try using the search option, top right corner of the page, that way the Dev's
don't to go reading 1000 posts of the same thing.
They are working on the next patch, which should include the ability to rebind keys for Left handed gamers, also seeing as you have a $4000 machine
you could go and buy http://www.cybersnipa.com/us/gaming-keyboards/gamepad.php which can be used left or right handed and is basiclly the WADS section of a keyboard
but is more comfortable for left handers.(no im not left handed but i do know plenty who use it.
