Her Q may be broken  because with max CDR it has 2.4sec CD, her old Q has 4.8sec CD with 2 uses per cast, but the new Q applies on-hit, deals more damage and triggers her passive.

Her old ultimate had (almost) no counterplay but her new ult doesn't fit her kit - it's like giving an execute ultimate to a support.
