Sion Q animation change suggestion

Watching the C9 TL finals, in game one I kept noticing that Sions smash as the indicator is charging to full, if released, the damage goes off in the full area of the skill, but that doesn't match the area of growth of the charge as indicated. So how do you know if you'll be in the AoE of his ability until the final instant of it going off, even though it never actually reaches there because the player releases the skill early. I think it should have a faded outline of the skill, then have that fill up highlighted as it's being charged, that way a player can know where they're standing in relation to the whole skills possible area. Anyone else see this too? Agree? Thoughts?
