Kat's new W feels very clunky
I really think you should be able to throw the dagger onto the ground away from you and not just right on top of yourself.
If you could toss the W dagger 250/300/350/400/450 units away (based on skill points spent) it would be such a powerful tool for chasing or setting up damage trades and make people actually want to put points into it. As it is right now it seems like a one point wonder and it feels really awkward to successfully hit somebody with the damage from it unless they just stand there and let you hit them.
Most of the time I found myself just using it for the speed boost or for waveclear.
