I fully agree. The game was probably designed around the idea of the player choosing one of the origin characters, Tav feels like an afterthought. But even with an origin character you have the problem of "competing narratives", like you are playing gale and it still would feel like, but the main character is someone else. Guess they were surprised by the numbers they are seeing. And act 3 is a mess, there is no other way of saying it. Act 3 is the equivalent of an unsupervised child in a candy store, too much of everything.
