I’ve had more luck streaming games with Moonlight (+ Sunlight server on game pc) than using Steam Link, both for controller support in certain games and just better latency. Even on Steam Deck, when I’m at home I barely notice a difference, it saves a lot of battery and I can AAA games without compromising in graphics settings.
Sabine does some pretty amazing things in Rebels. And she also doesn’t have to be as Force sensitive as Luke or Anakin, not every Jedi was. Obi Wan was considered a late bloomer.
I had objections about Sabine being a Jedi as well, but I think they’re explaining it pretty well. Talent is a factor.
