Chappers, I think you are looking back too much in your thinking. These characters haven't been taken away from you, but they are not part of the new series of Doctor Who and really don't belong in it. Jack is one character that might fit in at some point, but really even if not, I don't understand why you need to "miss" him or other characters unless you are not being permitted to watch the stories that feature him/them
I'm not sure if I am putting this well!
BTW I am a huge fan of Jacks character, both in DW and TW, so it's not a case of me not liking the character.
