Hear me out

Should nikke add away for you to evolve your sr characters into SSR but Morrow is not changing the designs as much but at least so you have a way to actually get a useful for the SR’s or should they add a form of an assisting slot to where you can have characters assist I don’t really know how to phrase these questions. OK so I’m raising it as it is should they let you evolve your characters or not or in this case upgrade?
