Can't shake off the feeling new Runic Echoes is a big slap to champions that use it today

I'm confident it's going to be worse on Evelynn and Elise, not entirely sure though about Nidalee or Diana. AP jungling champions never stroke me like some that need their mana pool extended in order to be effective. As it is right now, i never run into mana pool problems clearing the jungle, fighting with champions or whatever it is i'm spending it on. I guess the CDR can find it's use on any magical damage dealing jungler that isn't Evelynn, but mana instead of a 7% move speed? That's just not right. Nidalee can bypass that because she has terrain scaling, but for assasins like listed above this is a massive hit in my opinion. Additional move speed is a massive helper in terms of approaching targets as these champions, and I'm extremely disappointed in seeing these changes.
