Garlean PCs will never happen. Every job and class available uses magic--even the Disciples of War--to empower and guide their actions. Garleans cannot do this and can only get around this weakness by use of magitek, which has much stricter limits than real magic. Story characters left and right would have to make concessions for a Garlean WoL who is unable to wield the most basic of little magicks. Some game mechanics exist because this is a game and we need certain conveniences, but are sometimes referenced in the game lore, like our unusually abundant Anima that allows us to teleport all over the place while everyone else has to walk or take a boat. These would make no sense for a Garlean WoL, who would need to take the boat with everyone else. Things would just be really wrong if we could make a Garlean WoL.
