lol, didn't know there was a social group. And I agree with you that her legs are one of Saki's best feature, so it's a shame to see them mostly hidden now. I have no idea what Ritz was thinking when she decided to make her wear long skirts.
I don't do that for every episode. I've already read the manga so I only watch key scenes I'm dying to see animated.
Waiting for the HD version is definitely worth it. The nico stream quality looks like ass, it's so bad you can't even make out what's going in action heavy episode. The animation is also improved in the HD version sometimes. That was the case for episode 6 which had brand new animation during Illyarcher's fight.
So unless you really can't wait and are planning to watch both versions, I say you're better off sticking to the HD broadcast.
While I'm at it, I suggest you read the manga after the anime ends. It looks like you're enjoying the series so you're definitely going to love the second season of the manga. Everybody agrees it's a huge improvement over the first season. It's better in every single aspect. And it has tons of yuri!
I notice that you seem to be watching the earlier Prisma Illya episodes. Have you compared them to the ones that come out later? If so, do you feel that there is a significant visual quality difference?
I ask, because I know we both waited for the more HD episode for RDG, so if you're going early with Prisma Illya, maybe I should too.
