I just recently came back to STO and am not so clear on two traits in the new trait system -- Stubborn and Mental Discipline. Aren't these traits virtually the same thing? At first they specify slight differences, but I later find them in my ability pool for use as an active ability. Then they both pretty much indicate they break hold effects as active abilities.
Anyway, I ended up getting both; I like all the traits I picked except these two. If they are close to being the same I'd really like to dump one (probably mental discipline since my character started with Stubborn back when it was just a passive trait when the game began), and pick-up another much need space trait like Techie.
