What? According the redditors that permeate the game and the ae babies that do this very thing you speak of, it doesnt happen at all. Just like learn to play around them or something. Youre like spoiling the game or something. Aoe immob on autocast is like the best thing ever man. But people dont do that man. Like wow. I cant even.
Sadly the people that do this thing that never happens dont actually read the forums, chat, think beyond autocast aoe immob like its a really low damage fireball etc....
