The easiest way to make Annie fun to play against and have counterplay

Increase the cast time of tibbers.

That's it.

Don't reduce the damage, don't reduce the stun duration. Don't change her passive. Don't nerf her in ANY OTHER WAY.

All she needs to be a healthy champ is a longer cast time on her AoE hard CC nuke that comes with a skillshot blocker free of charge.

And if you REALLY want to keep flash Tibbers viable, make it so flash interrupts the cast time, making it instant-cast. This will make sure your shitty "LCS Big Plays" are still around, but Flash has to be paid for it, and without it, the spell is far more fun to play against.

And while we're on the subject of Annie, can we fix the Season 1 cone spell bugs? Cho's silence and Annie's stun and damage still affect you if you leave their range or become untargetable during their cast time. Why isn't this fixed yet?
