I don't see why it would matter to get 3 lines easily. Not like the rewards are anything special. It doesn't matter much, but for what you get, the chances are extremely low.

Anyway, what i want is for them to remove things i haven't and never will unlock from the list, and replace them with whatever i do have. No, Yoshida, i won't do your raids, your PvP nor your extremes no matter how much you like them and "encourage" people doing them. It won't work (and curse you for Crytal Tower).
