Every class has a different set of tropes attached, most likely so that everyone will find a class that suits them. I played enough of the Consular story to realize that set of tropes wasn't for me, but I'm not ready to say that it's a bad story because of this.
But, since I've no desire to play an SI, I've gone ahead and looked at much of the story line, and I agree with the OP that it's rather weak. In BW's defense, what they've done here is the equivalent of creating 8 movie scripts, and there's bound to be a couple duds. Overall, pretty impressive job, though.
