Anivia's Crystallize (Ice Wall) Quality of Life Buffs
Some Quality of Life buffs to Anivia's Ice Wall would be nice like making her wall actually knock-back enemies when it is first summoned just like Trundle's Pillar of Filth; also allowing her Ice Wall to grant assists when enemy champions are within a certain radius of her wall. Another utility buff would give a small radius slow field around the wall that chills units so that her Ice Wall even has synergy with Frostbite allowing Anivia to critically strike off of her wall for W-E comboes. On a side note: with mana sustain getting nerfed every season it could be worth considering lowering the mana costs on Glacial Storm (Anivia's ultimate).
