YES!!!
We lefties don't have many heroes, so having our biggest one taken away is absolutely uncool. I never understood why they didn't allow you to choose handedness since the Wii games - I want to play with motion controls too!
That was one of the worst things about the Wii. It was basically unplayable lefthanded unless it was a game that relied on gimmicks. If it was a standard thumbstick-to-move-and-buttons-to-do-things, it was always wrong. I either had to retrain my muscles to hold something wrong or do actions wrong.
BotW should have gone back to lefty, but I guess you could still play motion with JoyCons, so they left him righty...
At this rate, we're going back to when the only lefties in games are villains. I remember when Skyrim announced you could equip in either hand, but it wasn't true left-handedness, it was just using a sword in your off-hand while your on-hand punched. You couldn't block if you wanted to be lefty. And it also didn't include cinematic kills - I didn't realize they were in for ages until I had a dual-wielder.
