Its right!!! I played Darius before and i was nice. I did not ks if somebody had the kill but now if there are 3 enemis i will kill the first one. Somebody will take the second one and i will go for the third. If the ult is going to cooldown i will ks to reset the timer and i will strike the third with full power.

So the nerf is encouraging Darius to ks to reset the timer before cooldown to take another kill.
