I have no specific planet wishes since I never actually consumed any star wars media besides SWTOR itself, but I was actually quite happy with the framing around Onslaught itself. Having both new worlds and some material to expand on the progression on old worlds is something I can get behind as a "template."

It sort of makes sense to revisit Balmorra at some point, in a similar fashion to how we went back to Corellia, just because I'm unsure how they'd reintroduce Zenith in any other way besides that.
