Possible change for Annies Ult: Increase AoE a bit, add a cast delay with clear indication.
Bam, Annies Ult has Counterplay now.
Honestly, AoE Stun with no way to dodge it is broken, change it like that, no longer broken.
Bigger AoE because otherwise it would be too easy to dodge when it signals where it will land.
My suggestion: INcrease AoE by like 50%, add a casting delay of 0.75 seconds.
