Yeah, I noticed
youll be missed. Though I also have to admit its been nice playing in my own bracket :P Just finished a ~45minish game with 19/4/11! with katarina. Ahhh katarina, been itching to play her for awhile. Now that I finally have a handle on the game I don't wtf suck with her. But you are right, she's doesn't bring much to the table. She really only does well if your team is already doing well OR they have no CCers to stun you out of ult (in which case they prob arent doing well anyway).
I'm almost positive they don't but I figure I better ask just to be sure; Kat's bouncing blades or ult can't crit right? I woudn't think so but BB is one of the few abilites based on AtDmg and not AP so I'm not sure.
