Patch Available - JMS 3.39

and Kanna nerf from the looks of it.

I would say otherwise.

The main concern for Kanna (apart from the skill%s) were the Mana consumption/recovery.

I can see a few skills that like Aran's combo recharge and improvement to recovery rate, which I assume will be happily welcomed by Kannas. (then again their main attacking skill now uses more Mana.. I guess it's hard to tell how much an improvement it is to mana consumption:recovery rate until it's live)
