Its impossible to be a jedi by not mastering 5+ professions with one character. All the hype and BS about unique paths and crap was just that.. crap. SOE's short-bus riders the SWG team decided would be one of their features of their game.. but it was too hard for them to comprehend or took too much time from them playing their jedi chars on the internal server or decorating houses with stuff in game so they just slapped in the holocrons and that you have to master w-x-y-z professions which are randomly chosen for you.
If professions had nothing to do with Jedi I would have unlocked my slot a long time ago, as I travelled every where there was to go, did all the quests in game that weren't Imp only, went up rebel ranks, participated in PVP, visited all the POI's, started a PA, was an artisan, a dancer, a bio-engineer, a smuggler, a pistoleer, a commando, a CH, a brawler, a marksman, a medic, etc etc etc..
By saying they have no way of tracking which POI's we visited before the badges went live or what professions we mastered before the master profession badges went live just proves that they werent "tracking EVERYTHING in game" like they said they were.. its all a mindless grinding session to play your character over and over and over again til you find the magic set of masters that gets you your slot. Very boring and unimaginative. If you hate yourself, you could do this without reading any holocrons.. but theres a chance youre going to have to master allllll professions with one character.. where as the holocrons can narrow that down for you. If you still believe theres some really cool thought-out way to unlock your slot then you are mistaken.
