I have to agree. She is pretty bad.
She's 100% useless after 20 minutes, falls off harder than she ever did before. She has an ok-ish laning phase, but compared to the likes of Talon, Kata, Yas, Zed, any typical AP mid, she is just terrible later in the game compared to them.
They also slowed down a lot of her combos like W -> E. Now the animation has to completely finish before the E goes off, it's just so fucking bad, to the point the enemy doesn't even have to try to dodge it, they just run in a straight line and it won't get to them in time.
And as for the Clones from her mimic, 2.5s makes them useless. For the old passive, it lasted long enough champs couldn't just hold CDs until the clone died. Now, they don't have to guess, just wait 2.5s since she can't do anything to you until the sigil procs anyway, and blast her.
And RR is just.. complete utter garbage. Nobody even reacts to it, and it just kamikaze's instantly, completely unlike a real player would do. LB Can't even pick off low-hp targets anymore because they'll just nuke her before she can do anything. And good god that constant automatic laughing is so irritating, and also makes everyone BM you because they think you're doing it on purpose. It also makes you look like a fool because she isn't deceiving anyone with her tricks anymore
Just what were they thinking?????
