I've always wondered something... Why aren't the daggers allowed to be destroyed if you step on it?
I wouldn't mind being 100-0 more often by
if only her daggers were allowed to be destroyed by stepping on them, much like how you would step on Zyra's seeds and Poppy's passive shield.
That way, it rewards players who avoids her daggers and rewards Katarina for making smart use of her daggers too. Doesn't feel fair that her daggers are lying on the ground for a few seconds and you can't destroy. Walking close to the dagger now just means you'll have to take your chances.
Edit: Surprised this received so many responses. A lot of you are wondering why this was even suggested in the first place... To idea is to punish Katarina through limited mobility (or restricted numbers of Shunpo) rather than lowering her late game carry damage. This would only affect inexperienced Katarina players and make experienced ones strategize harder for a kill. As of now, just by the sight of daggers is enough to zone you out until it disappears off the ground, Katarina just needs to have two daggers on the floor in close distance and she has already created an area to push you away. Instead of backing away, waiting for 3 seconds and losing a few potential cs, on top of letting her push your lane and going to other lanes to roam, might as well take the risk to destroy her daggers and lower her lane pressure.
For those of you mentioning Poppy's shield stays longer on the ground, the duration is the same as Katarina's daggers. And, if you're concerned about thematic in that stepping on a dagger doesn't make sense because it hurts you... Fine, let's turn it in to destroying daggers by AA range. While we're at that, perhaps you could rationalize on how stepping on a hard shield to destroy it makes any sense either.
And lastly, those of you mentioning her daggers has a set amount of time in the air before it lands, that's not counterplay enough. Neither is walking diagonally nor back & forth, that's just like saying how cc screws over every other cancer champion. Either way, even if you do all that, post-6 she has ultimate to damage you. Whether a Katarina picks up her daggers or not, a Katarina jumping in to your face is going to guarantee a kill for her.
