When I think about classpect powers I try to think of them less as "a set of powers of said classpect" and more like "powers that fall under specific category". It helpes making things more varied. Why would two characters have samish lowers until they are so high level in their aspect powers that they can just do ~aspect thing~ anyway.
They’re broad and really up to each individual Player, really, yeah. High level doesn’t necessarily mean that they can just do everything though.
