Well, I think that it was only natural that Weiss would turn nicer, specially for two reasons:

1) It's quite annoying when a character is like the old Weiss and doesn't develop through the story. Their attitude turns extremely predictable and it usually ends up ruining the plot. I don't think they really want to make that happen at Roosterteeth.

2) Professor Port has given her some of the best advice of the series. I think that he has to himself more than it looks like, as he has most probably been capable of seeing through Weiss quite clearly. She has probably always been pushed to be the best student, the best fighter, the best singer, etc, and nobody has really treated her like a person or helped her develop as a person. Professor Port's advice is quite clear: "be the best person you can be". I think that was what ignited change on her, even though she probably needed all of the day for that.

So anyway, this is just what I believe.
