I don't know how many people here are aquatinted with the old SWG leveling system. When entering the game, we should not have to, at default, choose a profession, rather, we go through the game doing what we want to do to get to the goal. To clarify, in the old SWG system, you would enter the game as an avatar, on your profession sheet, you would, see if memory serves, all the possible profession trees, and in order to get each skill, you needed relevant experience. For example, if someone wanted to go Doctor, they would need to build xp, by healing people, or doing simulations, this xp will in turn allow you to acquire a new skill in that profession, but the xp would not be able to be used for, lets say combat. This would allow greater flexibility in STO among professions, Captain would be something almost everyone would want, so they would need, I think a more rounded experience plus, perhaps a minor concentration, Picard seemed to have diplomacy/tactical, Janeway, Science, etc. You in turn of course would be limited to a max amount of skill points obtainable.
