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

[Dererk]

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.

^ this right here. Also not to mention adding them to all 6 races.

6 races not to mention male and female genders so 12 in total.

12 x12= 24 separate cut scenes they'd have to make. So pretty much they decided it's much better to not do that and instead put the time and effort that it take do make 24 different cs into other stuff. Which is a good call.

While it be cool if our character did do something like fight in the cs its better to not waste time with it.

Ps. Not to mention they'd have to go back and add more once new jobs are in and if they ever add a new race.
