As you all know his ultimate is the channeling blizzard ability, After playing glacius 4-5 times I have had good ultimate and bad ultimates. For clarification a bad ultimate is when you ultimate an enemy at melee range while hes imprisoned and you dont get any procs of dmg, I just watch glacius spin while the enemy hero takes no dmg. And I've had good ultimate where in the same scenario where I have an enemy in an melee imprisonment where I get 5-6 procs of dmg destroying the enemy hero. I feel that the only hero that should deal with luck is heroes with crit / evasion and blacksmith. Why should such a stable and fragile hero like glacius have to worry about getting procs on an ultimate when hes easily the squishiest hero of all.
So what I propose is what you switch how his ultimate works.
I think it would be awesome if at the start of his ultimate, It would start at the base of glacius, and rotate outward circularly spinning like a trail until it reached the the max range and it would start back over at the base of glacius
just imagine a spiral pretty much. I would usually offer pics but im on a mac atm >_>
