Annie should literally throw Tibbers for her ulti. Not instant casting it
Basically as title says, i don't think that those istant stun with 0 counterplay have a healthy space in the game anymore.
Annie is too much of a terror when her stun and ulti is up, becouse well, you don't have any reaction time (especially if she flash + ult). Not only that but she has insane burst damage and insane AA range.
So i list here my fix for that.
For supp: • AA range should be lower • Tibbers should be a casted spell and shold be thrown in the air. When it lands you got tibbers (remember the cinematic?)
For midlane: • Tibbers should be a casted spell and shold be thrown in the air. When it lands you got tibbers (remember the cinematic?)
. And the like.
'Sup

The range is outranged by several spells, particularly from midlaners (Even Zed!)
It's difficult, but there is some counterplay beyond 0.
