Ahri's damage and her range

So I just played a match as Ahri and the entire match I felt like my damage was just not there. I mean Fox fire is kinda useless now and ahri's range on fox fire and spirit rush is less now plus the mana cost. My normal item rotation is however last match I had to rush hourglasss over deathcap for Zed and the whole time my damage just wasnt scaling to matter much idk. The way Ahri is now she is more of a kite mage than a rush in assassins like before. I mean my team was on me for not playing my role as an assassin and not rushing in. IDK i just felt like something was way off, any another ahri players having similar issues? I feel like I should just rush and first now. Any tips?
