I really hope they are the next pass, and of course for Luke to be the staple of a jedi team. GK is certainly above the scale of moderate players in the game due to his accessibility. I would love to see the jedi become more deeply balanced. They can certainly take top spots using their top contenders, but not anywhere near the same amount of depth as rebels. (Then again nothing is).
Mace, anakin, lumi, plo, old Ben, all of those older characters should get a rework to make them better then what they are currently. Similar to how the imperial troopers were buffed, not game breaking, but certainly fun to play with. And of course with Luke/kenobi/r2 combinations, they remain top end.
