Count Dooku using Sith lightning ruined the prestige.
I agree. That should have been an extra-high ability power unique to The Emperor.
Speaking as an A:TLA fan, I’m glad the show limited lightning bending to just Azula and Ozai (i.e., two royal family members who were bending prodigies). Korra did away with that limit (while the Kyoshi novels made it even rarer than the A:TLA). Still, it’s more understandable than making Sith Lightning so widespread.
I’m going off-topic, but I’m watching Avatar season 1 for the first time right now. I wonder if there’s a TLA thread in the off-topic section? I could see a lot of Star Wars fans being Avatar fans as well, like yourself.
A friend of mine loves A:LTA and Korra is the bane of his existence because of how it messed up the canon/lore. I’m glad I don’t hate the prequels that much, but they certainly did a similar thing.
