I assume it was an aborted arc. The creators probably thought Shae would be more relevant due to her constant presence. I would've preferred Tysha being given more importance too though.
Yeah it is critical in the books but then we had ancient midgets shooting magic grenades in this episode, so Tysha's exclusion was hardly the worst thing. Bloodraven's intro was alright even if he did look like Pycelle's brother.
