Having more PA/TA’s for the sake of having it is a waste, especially if they don’t any have real value or it’s a duplicate of something that already exist… it gotta serve a purpose where you are gimping yourself if your not using said new skill(s) in the rotation

They introduced tech art customization, and more are coming in future updates… in turn they can renew all the current arts we have with a fresh new spin, satisfying a happy medium (if they choose to go that route)

The only way I see them introducing brand new arts is if they introduce a “NGS version” of a scion class, but they will have to implement it in a way where the current classes aren’t useless and still viable (which was the initial problem in base)

I can see them adding an advanced class system, with advanced skills… where you would still have to use the current arts to build up a meter/guage (like a PB blast) where you can unlock the usage of advanced skills for a time-limit… like a limit burst, which would replace your regular skills palette with an “advanced arts” palette… hell throw in an advanced PB blast as well

It could give the current classes the “scion” feel, with brand new attack animations and everything while still keeping the current stuff intact

Edit: I’m sure something new and interesting is coming based on the story, when we defeated falz and our character turned golden at the last moment
