Her E's cooldown is 10 to 8 seconds and is maxed 2nd.
Just learn how her daggers work, she can't jump in any direction like she could before.
The time between jumps goes from 3 seconds to 0.4 seconds from level 1-18. She doesn't make CDR.
If you can't hit her in the 3-2 seconds she has before she jumps again after grabbing a dagger during laning phase, then thats on you. It really just sounds like you have no understanding of how she works.
2 seconds is a long time in close fights. It doesn't take anywhere near that time to land a skillshot on a kat that got in range to hit you with a dagger.
