A nice video. Superior, I'd say, to the disconnected fight scenes of A Twist of Fate. And Draven was pretty chill that whole time.
Too busy being shipped with Leona to act like her voice-lines would imply. And as a squishy mage, being afraid of 2-4 simultaneous enemies is the right call.
Ryze's model was totally creepy. I think they did better not going so close to live-action look. Because they never get quite far enough for it not to look weird.
This is all very good, but I would like to add that taking flash is unsportsmanlike, and should be limited to only Ranked, if at all.
Given Katarina's reaction just after, I think that was intentional of them.
