So would you like it better if they kept the force lightning unique to the emporer but all siths had a power unique to them? Like maybe Darth Maul could shoot fire outta his hands. Dooku could conjure water from the air and dirt and splash it in peoples faces. Or should all Siths be powerless and only the Emporer should have it cause he’s so evil.
That’s Avatar, not Star Wars.
(Not the dumb movie about the blue girl. The dumb cartoon about the bald boy.)
