+1 DJL. I’m a fan of (aggressively) removing or recontextualising anything which retroactively does damage to the rest of the saga, which I think lightside healing does. ROTS established that the power to create life is unnatural/darkside, and by extension I’d always assume healing is - especially since we don’t see it used by any Jedi.
I like the Sequel Trilogy, a lot, but I think that it has a lot of elements which harm the wider saga, or raise tricky questions. Compare that to Rogue One, which, whether you like it or not, it fits perfectly. It doesn’t break a thing.
