I liked your classes propositions but I would really be surprised that they actually create a brand new class, considering a new class would mean new dialogues and new actors to hire with all the financial factors/issues that come with that.
Nevertheless, they should at least create new Advanced Classes to pre-existing classes. Those are the real classes of the game, if you think about it. I mean, for isntance, Powertech and Mercenary are different in almost everything, but the story.
So at least new Advanced Classes would be really great. Like a DPS only Advanced Class for the Inq, or a Tank/Heal/DPS Advanced Class for the Bounty Hunter, or whatever they want for all i care, but something new to bring life into this hell of a game.
Right now, us, subs, are paying for the content that we already have paid for during years. At least something new would make this game a little more worth both our money and time.
Anyway, they will probably never do either of those possibilites
