It wouldn't work out currently. Programmers cannot simply "mirror the image" The way we run, move, use skills, auto attack, potions, and all of the like are all tied into our current dominate hand. All this would need to be changed a lot of skills would need to re-worked (chaos thrust -ex). This would also eat up a lot of memory (insert PS3 limitation comment here)

So as much as people would like this, it is a very low chance that it will be done for this MMO. (I'm talking sub 1%)
