Ik this question is weird coming from a guy whos only successful twink was a sorceror... But i got a few questions

Does the ice move for sorceror EVER stun? Does the wind move EVER knock back the opponent? (Ive come to notice fireballs stun is worthless. The DoT is the main reason i kept it. So now i have to figure out new skills to keep rogues DOWN!) THX!
