I've seen many broom parties in Limsa. They will forever remain undeterred. It's not a big deal to me either way. If it's annoying, I'll simply leave, but they aren't breaking any rules. But yeah, an option to turn off emote sounds wouldn't be a bad idea at all, in my opinion. They let us do it with Performance (best decision I've ever made). I don't see why that couldn't be extended to loud emotes, or just emotes in general.
