T.K. Baha worked because it was a small quest, he was not the main content of the DLC, the main content was Claptrap story, that worked great as well, do you know why? Because of “connection”.
Krieg in this dlc shows almost no emotions, he has no outburst, no breakdown, he just accepts what it is, that way we don’t connect with him. I didn’t feel bad for him losing Maya, because he didn’t feel bad about it too, he just accepted her death.
I didn’t feel sorry for the experiments they made to him, because he didn’t care that much about it either.
Even the end of the DLC shows how “cool with stuff” he is, he just accepts the psycho, he ALWAYS just accepts.
In claptastic and tiny tina, the characters have a breakdown (in claptastic the character has even a bad ending, being betrayed after all the good he did), we feel their pain.
