why during cutscene its always like this ... (small spoiler)

[Ashkendor]

and with the technology we have today, making kind of different class cut scene isnt much of a problem (many game already have this, why not here ?)

Because putting together a cutscene for every single one of our 12 battle classes would be pretty resource-intensive.

They all have completely different skills and fighting styles so it's not the kind of thing you can just kludge together.
