Annie!
Well, as I'm sure we've all seen in the LoLEsports stuff, Annie is.... becoming beyond a terror. And yes, I know, there's many that are going to defend her incredibly heavily, but... Why is she allowed to have such instantaneous stunning power? I mean, Veigar used to have the same, but they changed his because they felt their wasn't any counterplay to it, so instead of nerfing the range, they gave it a delay. Annie has two abilities that are both AoE and have less than .2s of delay. Her W is completely instance while her R has about a .2ish delay for her to throw the bear.
I should also note the only other AoE stuns are all delayed or can be dodged in some sort of way due to some kind of indicator. Leona's R has a small delay and her Q lights her shield up. Braums R has him jump up into the air, pointing at the direction of where he's going to toss it and his passive shows when you're going to get stunned to a certain degree. Sona's R shows her strum the cords and you even see the wave of light go at you. Zyra's E is like Sona's R and her own R is delayed just to do damage and further delayed before it actually knocks up. Malphite's and Hecarim's R have them charging at a location....
All in all, every form of AoE CC has a delay, long cooldown, low damage, or any of the combination of those. Annie's stun only has one indicator and that's the swirling smoke around her, but that doesn't tell you that it's coming, it simply says she can use it. She has no delays or any true indicators while having huge base damages.
What do you guys think? Should Annie get some delays of SOME kind or some travel time with her R to make her not so incredibly Dominant as a support?
