Let's take a moment and realize what riot has done to Zed
"Zed is a great example of a healthy assassin" ~ says riot.
Riot has proven themselves wrong, first, by decreasing his base attack damage AND the rate as which his attack speed increases. To many of you guys, it would be,"oh, it's just a 0.06 difference" but goes more in depth than that. So what is riot trying to do? Riot is trying to make
more of a champion that relies on using his SPELLS, not AAs. Which is odd, because most of the AD assassins rely on their auto attacks to poke, such as
and his q damage amplification.
And second,his ultimate and the new 1 second delay. Now what I think riot is trying to do here, is make Zed players play more safe with their ultimates. So what exactly do they mean by this? Let's take
and her ultimate against
and his. Normally, Zed would just ult, and juke Cassiopeia ultimate with his ultimate shadow, but now with the 1 second delay, Zed would have to rely on his ultimate AND his W shadow, to escape the Cassiopeia.
Now with these hits to Zed, I'm really starting to question what riot really thinks a "healthy assassin" really is.
