Katarina's been a lot of fun and I hope to have the guides out for her soon. On an unrelated note, I am resuming my streams soon on Twitch.tv: www.twitch.tv/ciderhelm As of the time this video was published, the wiki entry reads that Bouncing Blades will consume a mark but will not re-apply a new mark. This is incorrect: Bouncing Blades will consume a previous mark, dealing the bonus damage, but it will still apply a new mark. This is mildly important because it means you aren't going to be punished too hard if you don't follow a specific rotation after each kill (i.e. Q then Q again isn't going to cost you a bunch of damage).
