As soon as anivia was tuned down correctly to make her require skill; people freaked out
I don't think the anivia players realize how strong she is compared to other mids. She has a zac passive which makes her basically undivable 6-, and her stun combo can legit one shot you at level 6 with 100+ AP. If she's gotten an early kill, you're completely screwed, she can block you off with terrain, and doesn't need AP to do damage. Seeing a 10ish AP anivia bring down an adc to half hp just with her ice shard thing and ult was pretty dumb.
