Anivia "mini rework"

So aparently there have been talk about changing the way her E move (frostbite) interact with her Q and R. As you may know if you hit someone with your Q or R you E does 200% damage to them allowing for some sweet combos. Well now riot is planning to gut Anivia and change that. Her Q projectile will apply frost and the explosion of her Q will apply a debuff called "iced". Her R will apply the chill debuff but will only apply the iced AFTER THE ULT HAS REACHED ITS MAXED SIZE! Oh and did i mention that her E only does 150% damage to chilled targets whereas the full 200% on iced. In my opinion being an Anivia main this is complete bullshit. Do you guys think the change is justified?
