Lol it's actually very important to watch it without dubs. The show is filled with people interacting who don't speak the same language, which makes it interesting. Dubs ruin that. Netflix in their wisdom defaulted to dubs, and fortunately I learned to correct that after about three episodes.
That is rule even waiting for more than 2 seasons... But I forgot about it the other day when my wife and I wanted to find something fast to watch and selected Kaos :(. We didn't even intended to keep watching or expectations of enjoying it as much as we did. That sucks.
