My Questions for the Runes Reforged Dev Update Video

For those who havent seen: https://www.youtube.com/watch?v=bY67yCaGdno

As for my questions i really only have 3:

1. The new Runes system sounds like there is a lot of different more influential stuff you can do. However this also adds complexity, instead of a bunch of bonus stats you have gameplay choices. Do you have any precautions with the complexity of this new system?
2. Will Summoner Spell unlocks through leveling be affected by this rune/mastery change?
3. Will we still be able to honor "honorable opponents"?

Hopefully we can get some reds to answer some of these questions, so put your own questions from the video down.
