Only complaint about Katarina is trying to judge how long her daggers last.

New Katarina is surprisingly more difficult. More mobile. Less aoe. But higher early game kill potential. All seeming in line with what Riot wanted from her. My only complaint is the one stated in the title. Trying to judge the life of her daggers when focusing on all these other things seems a bit difficult. Maybe we could just get a red ring that fades as they expire.
