Annie/Tibbers doesn't stun all the time
Played several games as Annie lately aram/arurf and it seems like at least 1-2 times per game, while I have stacks built to stun on next cast and cast tibbers, it doesn't stun. Quite game breaking as that is annies move, flash tibbers/stun which gives you time to w/q and try getting out. Flash w/ tibbers not stunning just gets you melted hella fast. Sucks too because it burns up the 4 charges like the stun should have worked but it doesn't.
