Sejuani is gonna get banned picked for SURE LOL

"Passively, Sejuani and her melee allies apply Frost to enemies, and unlike Braum’s passive, Sej doesn’t need to be the one to start the stacking. Once a target’s reached max stacks, Sejuani can point-and-click stun them with Permafrost."

One of the things that people hate most and complains about. Remember taric's point and click stun? It has come back but in Sejuani's favor. HAHAHA. This is gonna be interesting.
