I'm pretty sure gift means that the original vision for this game was to create a role by the abilities you loaded on your bar as opposed to what your class says you are. Of course, whether or not that vision was a success or not is another discussion entirely. All in all, I think it was an original and interesting idea, and I really have to applaud SE for trying something new, but it really just doesn't work because it leaves the system too open and people just aren't sure what to do with it.
