It was intentional. Overall I think the only thing wrong from 8.4 was her waveclear got removed. She can't 100-0 anymore unless she is crazy fed so she pretty much has to poke someone down a little and then go all in. But she can't do that if she can't even get out from under tower.
8.5 is bringing her some buffs. From the sounds of it she has her waveclear back, and looking at the math of it she has more late game damage to her Q. So she's more of a scaling champ. It sounds like she won't be able to 100-0 anyone in the early game (again unless crazy fed) and thats the time to really harass her to try and keep her behind.
